release-notes: studio 2.59.0 carries the Noto Studio font change

-# Reasonix Mobile — the Android shell
-
-Runs Reasonix as an Android app: the kernel ships inside the APK and starts on the
-device, the interface is the same `desktop/frontend-next` build the desktop Studio
-serves, and the agent reaches servers over SSH.
-
-This file is for people building it. What a person installing it needs — what it
-does, how to pair with a computer, what it cannot do — belongs in the release
-notes.
-
-## One command
-
-```bash
-./scripts/build.sh release     # or debug
-```
-
-Three steps, in this order:
-
-1. `build-kernel.sh` → `app/src/main/jniLibs/arm64-v8a/libreasonix.so`
-2. `sync-page.sh` → `app/src/main/assets/page/`
-3. `./gradlew assembleRelease`
-
-Output: `app/build/outputs/apk/release/app-release.apk`
-
-The kernel and the page are **inputs to packaging, not Gradle build steps**.
-Running `gradle assembleRelease` on its own fails on purpose and names the script
-that produces whichever input is missing (`requireBuildInputs` in
-`app/build.gradle`): an APK with no kernel in it should not be buildable by
-accident.
-
-## Requirements
-
-| Component | Version |
-| --- | --- |
-| JDK | 21 (17 also works) |
-| Android SDK | `platforms;android-35`, `build-tools;35.0.0`, `platform-tools` |
-| Gradle | the committed wrapper, 8.14.3 (for AGP 8.11.1) |
-| Go | 1.26+ |
-| Node / pnpm | Node 24+ / pnpm 10 |
-
-```bash
-export ANDROID_HOME="$HOME/Android/Sdk"
-export ANDROID_SDK_ROOT="$ANDROID_HOME"
-export JAVA_HOME="/path/to/jdk-21"
-export PATH="$PATH:$(go env GOPATH)/bin"
-```
-
-`ANDROID_HOME` is the one thing nothing sets for you.
-
-## Scripts
-
-| Script | What it does |
-| --- | --- |
-| `build.sh [debug\|release]` | The whole chain |
-| `build-kernel.sh` | Cross-compiles the kernel only (`GOOS=android GOARCH=arm64 CGO_ENABLED=0`) |
-| `sync-page.sh` | Builds the frontend, copies `dist/` into assets, copies `LICENSE` |
-| `verify-page.sh` | **No phone needed**: starts the real kernel against the packaged page |
-| `run.sh [debug\|release]` | `adb install`, launch, follow the log |
-
-`verify-page.sh` is the one to run after a change: it starts the kernel with the
-same arguments `Kernel.kt` uses (`--auth token`, `--token-file`, `--port-file`,
-`-page`) and checks that it binds a port and answers 200. Without a device, that
-is as deep as the chain can be verified.
-
-## Where the code is
-
-| File | Owns |
-| --- | --- |
-| `MainActivity.kt` | The WebView, the back gesture, downloads, external links, renderer restart |
-| `Kernel.kt` | Unpacking the page, starting and stopping the kernel, waiting for the port, health probes, logs, the workspace directory |
-| `KernelService.kt` | The foreground service that keeps a long turn alive |
-| `NativeBridge.kt` | `@JavascriptInterface`: what the page may ask the phone for |
-| `BrowserShellServer.kt` | Loopback HTTP server the kernel's browser tools drive the overlay WebView through |
-| `Downloader.kt` | Writing a kernel-produced file through the system document picker |
-
-The page reaches the shell through `window.reasonixHost` and `ReasonixNative`,
-defined in `desktop/frontend-next/src/port/host.ts` (`AndroidHost`).
-
-**Phone and desktop share one page build.** What differs only on a phone is
-decided at runtime, not by a second set of components. `phoneShell()` in
-`src/port/host.ts` and the `[data-shell="android"]` selector in `mobile.css` both
-read `<html data-shell="android">`, which `index.html` sets before the bundle
-loads.
-
-One attribute feeding both is what keeps style and components from disagreeing
-about what a phone is.
-
-## What the page may ask the phone for
-
-`NativeBridge` is reachable from whatever document the WebView holds, so every
-method that touches the device asks `trusted()` first.
-
-The activity answers by comparing the **main frame's** origin against the
-kernel's and against the one paired computer the person scanned a code for. A
-page that navigated elsewhere is not trusted, even though it may still hold the
-object.
-
-Five methods answer without the check — `version`, `systemTheme`, `safeArea`,
-`setLayerOpen`, `setRunning` — because they report back what the page already
-knows about its own window and grant nothing.
-
-`openInApp(url)` is the pairing decision, not a navigation one: it loads a URL in
-this window only for the origin the scanner just returned, and only once.
-Without that, any page holding the kernel origin could hand itself the bridge.
-
-External links leave through the browser. A non-web scheme is routed to the
-system only for `mailto:` and `tel:`; everything else is dropped, because an
-`intent://` URL can start an arbitrary exported activity with caller-supplied
-extras.
-
-## Permissions, and what they cost
-
-`MANAGE_EXTERNAL_STORAGE` — opening a folder on the phone as a workspace. The
-kernel is a Go binary: it opens real paths with `open(2)`, and SAF hands back a
-`content://` URI it cannot open.
-
-Requested from the folder-picker action, never at launch. Android shows no dialog
-for it and opens system settings instead.
-
-**There is no OS-level sandbox around this kernel.** The PR sets the sandbox to
-off on Android, so confining the agent to the chosen folder is Reasonix's own
-write-root check and nothing else. A shell tool with all-files access can reach
-all shared storage.
-
-`REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` — Doze freezes the app group, which stops
-a turn that is still running. Asked once when a turn actually runs, never at
-launch, and the person can refuse. Refusing costs battery life during long turns
-and nothing else.
-
-**Google Play restricts this permission**: fine for a sideloaded build, a
-store-policy risk if this is ever listed.
-
-`FOREGROUND_SERVICE` / `FOREGROUND_SERVICE_DATA_SYNC` — keeping the kernel alive
-while the screen is off. `dataSync` is capped per 24 hours from Android 15. It is
-the closest honest description of "an agent is working".
-
-`CAMERA` — reading the pairing code a computer shows. Requested when the person
-asks to scan, never at launch. `ScanActivity` is not exported.
-
-`READ_EXTERNAL_STORAGE` / `WRITE_EXTERNAL_STORAGE` — the same folder walk below
-API 33. `maxSdkVersion`-gated; above 33 they are superseded by the permission
-above.
-
-`allowBackup=false` with explicit extraction rules, so a `keystore` or a token in
-app storage never leaves the device in a cloud backup.
-
-## Cleartext HTTP
-
-The kernel serves its page on `127.0.0.1:<port>`, and a paired computer serves
-the same page over its LAN address. Both are plain HTTP.
-
-Neither address can be written into a `network-security-config`: the port is
-chosen at start, the LAN address at scan time, and the format matches literals
-and domains, not subnets.
-
-So the config permits cleartext and the boundary is in the code instead.
-`shouldOverrideUrlLoading` sends every other http(s) origin to the browser, and
-the bridge answers only the kernel and the just-paired computer. A plaintext page
-on the LAN cannot become the document holding the bridge.
-
-## What goes into the APK
-
-| Content | Size | Why it is shaped this way |
-| --- | --- | --- |
-| `lib/arm64-v8a/libreasonix.so` | 45 MB | Go static binary, stripped. It is a `.so` rather than a file in `assets/` because only `nativeLibraryDir` is guaranteed executable — a binary copied to app storage fails on a device whose data partition is mounted `noexec`. |
-| `assets/page/` | 14 MB | The frontend build, including the Inter and Noto Sans SC fonts, `noCompress` |
-| `assets/LICENSE` | 1 KB | The repository's MIT licence, verbatim. MIT requires the notice and the licence text to accompany a binary distribution. |
-
-`assets/LICENSE` is generated by `sync-page.sh` from the repository's root
-`LICENSE`, not committed a second time: a checked-in copy drifts when the root
-file is updated.
-
-It sits in `assets/` rather than `assets/page/` because that directory is removed
-and rebuilt on every build.
-
-A release APK is about 31 MB.
-
-## Building
-
-**The Gradle wrapper is committed**, jar and all. `build.sh` refuses to run
-without `gradlew` rather than generating one from whatever `gradle` is on `PATH`:
-the dependency versions are part of the build.
-
-`gradle-wrapper.properties` pins `distributionSha256Sum`, so a mirror that serves
-a different distribution zip fails verification instead of being unpacked and
-run. Dependency repositories are the official ones only — a mirror belongs in a
-user-level init script.
-
-**Signing.** A release with no key configured comes out **unsigned**
-(`app-release-unsigned.apk`) with a warning. It used to fall back to the debug
-key, which produced an artifact that looked shippable and was signed by a
-per-machine key nobody chose: it could not install over the previous build.
-
-Point the build at a real key by writing `keystore/keystore.properties`
-(`storeFile`, `storePassword`, `keyAlias`, and optionally `keyPassword`) or by
-setting the matching `REASONIX_KEYSTORE*` environment variables. Key material
-stays out of the repository and out of build logs.
-
-Debug builds always use the debug key. Signing a debug build with the release key
-would let anyone who can read the keystore produce a build that installs over the
-shipped one under the same signature.
-
-**Non-ASCII checkout paths.** AGP refuses to build under a path with non-ASCII
-characters on Windows unless `android.overridePathCheck=true` is set. That is a
-property of one machine's disk layout, not of this project, so it is not in the
-repository's `gradle.properties`.
-
-Set it in a user-level `~/.gradle/gradle.properties` or pass
-`-Pandroid.overridePathCheck=true`.

- * The Go kernel (`internal/platform/browser/shell.go`) drives a WebView by
- * POSTing JSON to a handful of paths on 127.0.0.1. This class is the other end
- * of that conversation: it accepts connections on a random port, parses the
- * minimal HTTP the kernel sends, and translates each path into an operation on
- * the overlay WebView.
- *
- * The server is deliberately tiny — no connection pooling, no keep-alive, no
- * chunked encoding — because the kernel is its only client and sends one
- * request per connection. A `ServerSocket` accept loop on a daemon thread is
- * the whole transport; each request is handled synchronously on its own thread.
- *
- * WebView operations must run on the UI thread. Each handler posts to the main
- * looper and waits on a latch, with a timeout that bounds the worst case (a
- * page that hangs the JS thread) to something the kernel's own 30-second client
- * timeout will not outlast.
- *
- * Memory note on `/screenshot`: a full-page `WebView.draw` into an ARGB_8888
- * bitmap at device resolution can reach tens of MB for a long page. The bitmap
- * is downsampled by a factor of 2 in each dimension before PNG encoding, which
- * keeps the peak allocation under ~10 MB for a typical 1080p viewport. The
- * original is recycled immediately after the downsample.

- *
- * The shape is the desktop host's (`cmd/reasonix-studio-host`), narrowed to what
- * a phone does not have. That host binds a socket, mints a credential, speaks a
- * handshake down a pipe and holds a lease; here the credential goes through
- * `--token-file` and the bound address through `--port-file`, because a phone's
- * app process has no pipe to hand a child and no reason to care which port was
- * free. Everything after that — the kernel's own gate, its auth middleware, its
- * CSRF check — is untouched, so the security of the surface is the one upstream
- * tested, not one this shell invented.
- *
- * One instance lives in the app process. The activity asks it for a URL; the
- * foreground service asks it to stay alive. Both see the same process, so there
- * is nothing to synchronise beyond a lock on start/stop.

- * content is a web page: every method here is reachable by anything that can run
- * script in that page, so each one is written as a verb with no address
- * parameter it does not need, and none of them can name a path outside the
- * kernel's own home.
- *
- * It is deliberately *not* the Electron preload bridge. That one exposes window
- * management, a filesystem walker, an editor launcher and a browser view host —
- * all of which are meaningless on a phone, and the two that were not (open a URL,
- * save a file) already have a way to happen here: `WebViewClient` routes external
- * links to the browser, and the page's own download reaches the WebView's
- * `DownloadListener`.
- *
- * The one thing a phone must add is `importIntoHome`: the kernel runs on this
- * device and can only read paths under its own home, so a private key the person
- * has in their Documents folder has to be copied across. Nothing else the page
- * wants is out of its reach.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:

-#   (2) This script targets any POSIX shell, so it avoids extensions provided

-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
