ci: read main's sccache on every run, write it only from main

The sccache install step now runs on every event in ci.yml and
ci-test-suite.yml, and each Enable sccache step sets
SCCACHE_GHA_RW_MODE to READ_WRITE only on refs/heads/main and READ_ONLY
everywhere else (sccache docs/GHA.md; the action installs the latest
release, v0.19.0). Pull request and branch-dispatch runs, which now run
the full sharded suite, get main's compiler cache hits without writing
the refs/pull/N entries that once pushed the repo past its 10 GiB cache
cap. rust-cache save-if stays main-only and the Windows RUSTC_WRAPPER
guard from MAIN-GREEN is unchanged.

release-workflows.test.js now checks, per file, that every sccache
enable carries the off-main read-only switch and that no sccache install
is gated on main; both checks were confirmed to fail on a mutated copy.

Windows test legs keep debug 0: no test asserts on backtrace content
(only RUST_BACKTRACE pass-through lists and compile-time
Location::caller, which debug info does not affect).

Checks: node .github/scripts/release-workflows.test.js passed (211
paths, 11 wrapper cases x 12 steps, 15 hermetic checks, workflow
contracts); actionlint 1.7.12 with the repo's CI args (-ignore SC2129
-ignore SC2221 -ignore SC2222) clean on all workflows;
scripts/test_ci_migration_wiring.py 19 tests OK.

First drafted by a duplicate agent run in this worktree; reviewed and
tightened here.

 ## [Unreleased]
 
+- **Renaming sessions with Chinese titles:** the session picker no longer rejects a Chinese, Japanese, Korean or emoji title of more than about 33 characters as "Title must be 1–100 characters". It now counts characters, as the message says and as `/rename` and the Runtime API already did, so any title up to 100 characters is accepted. Thanks [@luochen211](https://github.com/luochen211) (PR 7322).
+- **Non-ASCII file names:** `/diff`, the `@git` and `@diff` mentions and the Runtime API workspace diff now show paths with Chinese, emoji and other non-ASCII characters as written instead of as quoted octal escapes, and the turn context no longer lists the workspace root as an empty "Active paths" entry. Thanks [@luochen211](https://github.com/luochen211) (PR 7317).
+- **Session names after a crash, and keep-forever snapshot retention:** a session name saved right after a crash that cut off the previous session-index line is no longer lost, because the new entry now starts on its own line; and a very large `[snapshots] max_age_days` (such as `9223372036854775807` for "keep forever") no longer wraps around and deletes every undo snapshot at session start. Thanks [@luochen211](https://github.com/luochen211) (PR 7316).
+- **Blank environment variables:** exporting a variable empty (for example `CODEWHALE_MODEL=` from a compose `${VAR:-}` template) no longer hides its legacy alias. `DEEPSEEK_MODEL`, `DEEPSEEK_BASE_URL`, `KIMI_BASE_URL`, `DEEPSEEK_FORCE_HTTP1`, `DEEPSEEK_STREAM_OPEN_TIMEOUT_SECS` and the other provider alias variables now apply as they do when the primary is unset. Thanks [@luochen211](https://github.com/luochen211) (PR 7315).
+- **Qwen Code as an external agent:** Codewhale now finds an installed Qwen Code CLI (`qwen`, 0.6.1 or newer) and can run it as a session over ACP with `qwen --acp`. `GET /v1/agents/external` lists it, an older install is reported as needing `npm i -g @qwen-code/qwen-code@latest`, and sign-in stays inside Qwen Code (`/auth`). Thanks [@MannXo](https://github.com/MannXo) (#7293).
 - **README and contributor credit:** the repository front page now opens the way the website does: the line "The model can be anyone's. The agent should be yours.", one sentence on what Codewhale is, the install command and one picture, with reference detail moved into the linked guides; the 18 translated READMEs follow the same structure and say they are machine-drafted. The contributor wall and the website now count the same 433 people (407 GitHub accounts and the commit authors whose email is not linked to an account), where the website had counted accounts only. `DEPENDENCY_SECURITY.md` moved into `docs/dependency-maintenance.md`, and `.github/SUPPORT.md` says where to ask for help.
 - **Website Plugins page:** The website's Plugins page now describes what the released version does, and a labelled section says what 0.10.3 adds: one Plugins place, Standard and Creator mode, and the Permissions control.
 - **Plugin docs and plugin-creator:** Docs now say everything you add is a plugin. The bundled plugin-creator skill no longer tells an agent never to trust or enable a plugin (in Full Access it may, for one it wrote and installed from its project), points code and screen plugins at cordis-plugin-development, and an untouched copy from 0.10.2 now upgrades. The Chinese extension and Runtime API docs now say editor ACP sessions get plugin tools and configured MCP servers.

crates/tui/CHANGELOG.md

@@ -7,6 +7,11 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [Unreleased]
 
+- **Renaming sessions with Chinese titles:** the session picker no longer rejects a Chinese, Japanese, Korean or emoji title of more than about 33 characters as "Title must be 1–100 characters". It now counts characters, as the message says and as `/rename` and the Runtime API already did, so any title up to 100 characters is accepted. Thanks [@luochen211](https://github.com/luochen211) (PR 7322).
+- **Non-ASCII file names:** `/diff`, the `@git` and `@diff` mentions and the Runtime API workspace diff now show paths with Chinese, emoji and other non-ASCII characters as written instead of as quoted octal escapes, and the turn context no longer lists the workspace root as an empty "Active paths" entry. Thanks [@luochen211](https://github.com/luochen211) (PR 7317).
+- **Session names after a crash, and keep-forever snapshot retention:** a session name saved right after a crash that cut off the previous session-index line is no longer lost, because the new entry now starts on its own line; and a very large `[snapshots] max_age_days` (such as `9223372036854775807` for "keep forever") no longer wraps around and deletes every undo snapshot at session start. Thanks [@luochen211](https://github.com/luochen211) (PR 7316).
+- **Blank environment variables:** exporting a variable empty (for example `CODEWHALE_MODEL=` from a compose `${VAR:-}` template) no longer hides its legacy alias. `DEEPSEEK_MODEL`, `DEEPSEEK_BASE_URL`, `KIMI_BASE_URL`, `DEEPSEEK_FORCE_HTTP1`, `DEEPSEEK_STREAM_OPEN_TIMEOUT_SECS` and the other provider alias variables now apply as they do when the primary is unset. Thanks [@luochen211](https://github.com/luochen211) (PR 7315).
+- **Qwen Code as an external agent:** Codewhale now finds an installed Qwen Code CLI (`qwen`, 0.6.1 or newer) and can run it as a session over ACP with `qwen --acp`. `GET /v1/agents/external` lists it, an older install is reported as needing `npm i -g @qwen-code/qwen-code@latest`, and sign-in stays inside Qwen Code (`/auth`). Thanks [@MannXo](https://github.com/MannXo) (#7293).
 - **README and contributor credit:** the repository front page now opens the way the website does: the line "The model can be anyone's. The agent should be yours.", one sentence on what Codewhale is, the install command and one picture, with reference detail moved into the linked guides; the 18 translated READMEs follow the same structure and say they are machine-drafted. The contributor wall and the website now count the same 433 people (407 GitHub accounts and the commit authors whose email is not linked to an account), where the website had counted accounts only. `DEPENDENCY_SECURITY.md` moved into `docs/dependency-maintenance.md`, and `.github/SUPPORT.md` says where to ask for help.
 - **Website Plugins page:** The website's Plugins page now describes what the released version does, and a labelled section says what 0.10.3 adds: one Plugins place, Standard and Creator mode, and the Permissions control.
 - **Plugin docs and plugin-creator:** Docs now say everything you add is a plugin. The bundled plugin-creator skill no longer tells an agent never to trust or enable a plugin (in Full Access it may, for one it wrote and installed from its project), points code and screen plugins at cordis-plugin-development, and an untouched copy from 0.10.2 now upgrades. The Chinese extension and Runtime API docs now say editor ACP sessions get plugin tools and configured MCP servers.

It serves the full HTTP/SSE runtime\nAPI (`/v1/*`), a JSON-RPC control transport over stdio, and the phone-friendly\nmobile page. `codewhale doctor --json` provides machine-readable health, and\n`codewhale serve --acp` speaks the Agent Client Protocol over stdio for editors\nsuch as Zed.\n\n`codewhale serve --http` / `serve --mobile` remain as **compatibility aliases**\nfor `codewhale app-server --http` / `--mobile`; both launch the identical\nserver. Desktop, web, SDK and custom integrations should target\n`app-server --http`. `--stdio` and `--socket` expose compatibility controls.\nBare `app-server` selects initialized JSONL control over stdio. Local stdio,\nsocket and ACP owners do not bind a hidden TCP listener. Explicit `--http`\nretains HTTP/SSE and compatibility routes on the same Runtime owner.\n\n`codewhale exec` is the separate one-shot headless worker path (stream-json,\nfleet worker subprocess, CI primitive).

It serves the full HTTP/SSE runtime\nAPI (`/v1/*`), a JSON-RPC control transport over stdio, and the phone-friendly\nmobile page. `codewhale doctor --json` provides machine-readable health, and\n`codewhale serve --acp` speaks the Agent Client Protocol over stdio for editors\nsuch as Zed.\n\n`codewhale serve --http` / `serve --mobile` remain as **compatibility aliases**\nfor `codewhale app-server --http` / `--mobile`; both launch the identical\nserver. Desktop, web, SDK and custom integrations should target\n`app-server --http`. `--stdio` and `--socket` expose compatibility controls.\nBare `app-server` selects initialized JSONL control over stdio. Local stdio,\nsocket and ACP owners do not bind a hidden TCP listener. Explicit `--http`\nretains HTTP/SSE and compatibility routes on the same Runtime owner.\n\n`codewhale exec` is the separate one-shot headless worker path (stream-json,\nfleet worker subprocess, CI primitive). It is not part of this API, but it\nshares the same runtime, provider/model resolution, permission profiles, and\nevent vocabulary.\n\nThis document is the stable integration contract for native workbench\napplications (and other local supervisors) that embed the Codewhale Engine.\n\n## Architecture\n\n```\nlocal supervisor / SDK / automation harness\n        │\n        ├─ codewhale app-server --http     → HTTP/SSE runtime API (/v1/*)        [canonical]\n        ├─ codewhale app-server --mobile   → runtime API + mobile control page\n        ├─ codewhale app-server --stdio    → JSON-RPC control transport over stdio\n        ├─ codewhale app-server --socket   → same JSON-RPC over a unix domain socket (desktop daemon)\n        ├─ codewhale doctor --json         → machine-readable health & capability\n        ├─ codewhale serve --acp           → ACP stdio agent for editors such as Zed\n        ├─ codewhale serve --mcp           → MCP stdio server\n        ├─ codewhale serve --http/--mobile → legacy aliases for `app-server --http/--mobile`\n        └─ codewhale exec [args]           → one-shot headless worker (stream-json)\n```\n\nThe engine runs as a local-only process.
