feat(core): wire v2 subagent tool

Checkpoint of the safe subagent slice:
- SessionExecution.awaitIdle (coordinator drain-to-quiescence loop)
- SessionV2.wait delegates to awaitIdle; drop unavailable error + handler catch
- SessionV2.create: parentID/title, optional location inherited from parent
- subagent tool file (core/src/tool/subagent.ts) NOT yet wired into the node
  graph; wiring the global SessionV2 dep from a location-scoped tool is the open
  problem being experimented on next.

+# V2 CLI and TUI development guide
+
+## Migration context
+
+- The TUI is being ported from legacy APIs to the new V2 APIs. New and migrated TUI behavior should use `sdk.client.v2` and the location-scoped data in `packages/tui/src/context/data.tsx` instead of adding dependencies on legacy sync state.
+- Preserve established TUI behavior unless the task intentionally changes it. When behavior, copy, keyboard interaction, or layout is unclear, compare the local V2 TUI with the latest released legacy TUI.
+- Run both versions in separate Terminal Control sessions and save PNG-only captures at equivalent states:
+
+```bash
+# From packages/cli: local V2 TUI
+termctrl start opencode-v2-dev --host opentui --cols 112 --rows 34 -- bun dev --standalone
+
+# Released legacy TUI behavior reference
+termctrl start opencode-legacy --host opentui --cols 112 --rows 34 -- bunx opencode-ai@latest
+
+termctrl save opencode-v2-dev --format png --out /tmp/opencode/v2.png
+termctrl save opencode-legacy --format png --out /tmp/opencode/legacy.png
+```
+
+- Use the same viewport and send equivalent inputs to both sessions before comparing screenshots. The released CLI is a behavioral reference, not a source of V2 API design; keep the local implementation on V2 endpoints.
+- Stop both sessions after comparison: `termctrl stop opencode-v2-dev` and `termctrl stop opencode-legacy`.
+
+## Interactive debugging
+
+- This package is the V2 CLI adapter. Run its `dev` script when testing the TUI; do not use the repository-root `bun dev`, which launches the legacy `packages/opencode` CLI.
+- Run commands from `packages/cli`. Use `bun dev --standalone` for most debugging so the TUI starts with a private V2 server instead of depending on the background service.
+- Use `termctrl` for interactive checks instead of starting the TUI as a blocking foreground process. It provides a real PTY, handles OpenTUI's host handshake, and can save reviewable screenshots.
+- Use a dedicated session name and do not reuse or kill an unrelated session.
+
+```bash
+termctrl start opencode-v2-dev --host opentui --cols 112 --rows 34 -- bun dev --standalone
+termctrl wait opencode-v2-dev "Ask anything" --timeout 20000
+termctrl show opencode-v2-dev
+```
+
+- Wait for visible text before interacting instead of relying on fixed sleeps. Use the text expected from the screen under test, such as `Ask anything` or `Connect a provider`.
+- Drive the running TUI with `termctrl send`. Prefix typed input with `text:` and send control keys separately so the interaction matches real terminal input.
+
+```bash
+termctrl send opencode-v2-dev 'text:example prompt' enter
+termctrl send opencode-v2-dev ctrl-c
+```
+
+- Use `termctrl show` after each meaningful interaction and inspect the full visible screen for rendering errors, stale state, error toasts, and unexpected exits.
+- Save PNG evidence for every user-visible bug and fix. Do not save text captures; inspect the rendered PNG. Write temporary captures outside the repository unless the artifact is intended to be committed.
+
+```bash
+termctrl save opencode-v2-dev --format png --out /tmp/opencode/v2-tui.png
+```
+
+- For resize-sensitive changes, resize the viewport, wait for the expected content, and capture the screen again:
+
+```bash
+termctrl resize opencode-v2-dev --cols 100 --rows 30
+termctrl show opencode-v2-dev
+```
+
+- Source changes may require restarting the process. Use `termctrl restart opencode-v2-dev` rather than assuming the running TUI reloaded the change.
+- To exercise background-service behavior, omit `--standalone`. Service lifecycle commands are available through `bun dev service start`, `bun dev service status`, and `bun dev service stop`.
+- Always clean up the Terminal Control session when the check is complete:
+
+```bash
+termctrl stop opencode-v2-dev
+```
+
+## Server/API debugging
+
+- Use `bun dev api --help` from `packages/cli` to inspect the API debugging command. It sends one request to the V2 server using the same daemon discovery/auth path as the CLI.
+- Use `bun dev api` to introspect the server-side data backing the TUI. This is useful when debugging UI bugs: compare what the screen renders with the raw session, message, event, agent, or health data returned by the API to determine whether the bug is in the server state, the client data layer, or the TUI rendering.
+- `bun dev api` accepts either an OpenAPI operation ID or a raw HTTP method plus path:
+
+```bash
+bun dev api get /health
+bun dev api get /openapi.json
+bun dev api <operationId> --param key=value
+```
+
+- Pass JSON request bodies with `--data`/`-d`; the command sets `content-type: application/json` automatically unless you provide a header. Add extra headers with `--header`/`-H name:value`.
+- If no compatible background server is registered, `bun dev api` starts one through the daemon service. Use `bun dev service status`, `bun dev service restart`, and `bun dev service stop` when you need explicit lifecycle control.
+- Prefer raw method/path calls for quick server debugging and operation IDs when exercising documented OpenAPI routes with path or query parameters.
+
+## Debugger
+
+- To debug the V2 CLI or TUI with Bun's inspector, launch the CLI entrypoint through Terminal Control with an inspector URL, then attach a debugger to that URL:
+
+```bash
+termctrl start opencode-v2-debug --host opentui --cols 112 --rows 34 -- \
+  bun run --inspect=ws://localhost:6499/ src/index.ts --standalone
+```
+
+- Use `--inspect-wait` or `--inspect-brk` when execution must pause until the debugger attaches.
+- Use `termctrl logs opencode-v2-debug` for inspector output or startup failures emitted before the TUI renderer starts. Use `termctrl show` for the visible full-screen TUI.
+
+## Verification
+
+- Run `bun typecheck` from `packages/cli` after CLI adapter changes.
+- Run `bun typecheck` and `bun test` from `packages/tui` after shared TUI changes. Do not run tests from the repository root.
+- Treat automated checks and Terminal Control smoke tests as complementary. For user-visible changes, verify initial render, the changed interaction, Ctrl-C exit behavior, and save a screenshot of the corrected state.

-## Database
+`packages/opencode` is the V1 version of this project.
 
-- **Schema**: Drizzle schema lives in `packages/core/src/**/*.sql.ts`.
-- **Migrations**: database migrations live in `packages/core` and are applied by core.

-## Development server

-- Running `bun dev` from `packages/opencode` starts the live interactive TUI. Do not run it as a blocking foreground command when you need to inspect the result.
-- Start it in `tmux` instead: `tmux new-session -d -s opencode-dev 'bun dev'`.
-- Capture the current TUI output with: `tmux capture-pane -pt opencode-dev`.
-- Stop the session explicitly when done: `tmux kill-session -t opencode-dev`.

-# Module shape
-
-Do not use `export namespace Foo { ... }` for module organization. It is not
-standard ESM, it prevents tree-shaking, and it breaks Node's native TypeScript
-runner. Use flat top-level exports combined with a self-reexport at the bottom
-of the file:
-
-```ts
-// src/foo/foo.ts
-export interface Interface { ... }
-export class Service extends Context.Service<Service, Interface>()("@opencode/Foo") {}
-export const layer = Layer.effect(Service, ...)
-export const defaultLayer = layer.pipe(...)
-
-export * as Foo from "./foo"
-```
-
-Consumers import the namespace projection:
-
-```ts
-import { Foo } from "@/foo/foo"
-
-yield * Foo.Service
-Foo.layer
-Foo.defaultLayer
-```
-
-Namespace-private helpers stay as non-exported top-level declarations in the
-same file — they remain inaccessible to consumers (they are not projected by
-`export * as`) but are usable by the file's own code.
-
-## When the file is an `index.ts`
-
-If the module is `foo/index.ts` (single-namespace directory), use `"."` for
-the self-reexport source rather than `"./index"`:
-
-```ts
-// src/foo/index.ts
-export const thing = ...
-
-export * as Foo from "."
-```
-
-## Multi-sibling directories
-
-For directories with several independent modules (e.g. `src/session/`,
-`src/config/`), keep each sibling as its own file with its own self-reexport,
-and do not add a barrel `index.ts`. Consumers import the specific sibling:
-
-```ts
-import { SessionRetry } from "@/session/retry"
-import { SessionStatus } from "@/session/status"
-```
-
-Barrels in multi-sibling directories force every import through the barrel to
-evaluate every sibling, which defeats tree-shaking and slows module load.
-
-# opencode Effect rules
-
-Use these rules when writing or migrating Effect code.
-
-See `specs/effect/migration.md` for the compact pattern reference and examples.
-
-## Core
-
-- Use `Effect.gen(function* () { ... })` for composition.
-- Use `Effect.fn("Domain.method")` for named/traced effects and `Effect.fnUntraced` for internal helpers.
-- `Effect.fn` / `Effect.fnUntraced` accept pipeable operators as extra arguments, so avoid unnecessary outer `.pipe()` wrappers.
-- Use `Effect.callback` for callback-based APIs.
-- Use `Effect.void` instead of `Effect.succeed(undefined)` or `Effect.succeed(void 0)`.
-- Prefer `DateTime.nowAsDate` over `new Date(yield* Clock.currentTimeMillis)` when you need a `Date`.
-
-## Module conventions
-
-- In `src/config`, follow the existing self-export pattern at the top of the file (for example `export * as ConfigAgent from "./agent"`) when adding a new config module.
-
-## Schemas and errors
-
-- Use `Schema.Class` for multi-field data.
-- Use branded schemas (`Schema.brand`) for single-value types.
-- Use `Schema.TaggedErrorClass` for typed errors.
-- Use `Schema.Defect` instead of `unknown` for defect-like causes.
-- In `Effect.gen` / `Effect.fn`, prefer `yield* new MyError(...)` over `yield* Effect.fail(new MyError(...))` for direct early-failure branches.
-
-## Runtime vs InstanceState
-
-- Use `makeRuntime` (from `src/effect/run-service.ts`) for all services. It returns `{ runPromise, runFork, runCallback }` backed by a shared `memoMap` that deduplicates layers.
-- Use `InstanceState` (from `src/effect/instance-state.ts`) for per-directory or per-project state that needs per-instance cleanup. It uses `ScopedCache` keyed by directory — each open project gets its own state, automatically cleaned up on disposal.
-- If two open directories should not share one copy of the service, it needs `InstanceState`.
-- Do the work directly in the `InstanceState.make` closure — `ScopedCache` handles run-once semantics. Don't add fibers, `ensure()` callbacks, or `started` flags on top.
-- Use `Effect.addFinalizer` or `Effect.acquireRelease` inside the `InstanceState.make` closure for cleanup (subscriptions, process teardown, etc.).
-- Use `Effect.forkScoped` inside the closure for background stream consumers — the fiber is interrupted when the instance is disposed.
-- To make a service's `init()` non-blocking, fork `InstanceState.get(state)` at the `init()` call site (e.g. `Effect.forkIn(scope)`), not by forking work inside the `InstanceState.make` closure. Forking inside the closure leaves state incomplete for other methods that read it.
-- `src/project/bootstrap.ts` already wraps every service `init()` in `Effect.forkDetach`, so `init()` is fire-and-forget in production. Keep `init()` methods synchronous internally; the caller controls concurrency.
-
-## Effect v4 beta API
-
-- `Effect.fork` and `Effect.forkDaemon` do not exist. Use `Effect.forkIn(scope)` to fork a fiber into a specific scope.
-
-## Preferred Effect services
-
-- In effectified services, prefer yielding existing Effect services over dropping down to ad hoc platform APIs.
-- Prefer `FileSystem.FileSystem` instead of raw `fs/promises` for effectful file I/O.
-- Prefer `ChildProcessSpawner.ChildProcessSpawner` with `ChildProcess.make(...)` instead of custom process wrappers.
-- Prefer `HttpClient.HttpClient` instead of raw `fetch`.
-- Prefer `Path.Path`, `Config`, `Clock`, and `DateTime` when those concerns are already inside Effect code.
-- For background loops or scheduled tasks, use `Effect.repeat` or `Effect.schedule` with `Effect.forkScoped` in the layer definition.
-
-## Effect.cached for deduplication
-
-Use `Effect.cached` when multiple concurrent callers should share a single in-flight computation rather than storing `Fiber | undefined` or `Promise | undefined` manually. See `specs/effect/migration.md` for the full pattern.
-
-## Callback boundaries
-
-Use `EffectBridge` for native or external callbacks (`@parcel/watcher`, `node-pty`, native `fs.watch`, plugin callbacks, etc.) that need to re-enter Effect services with instance/workspace context.
-
-Plain async code should pass explicit context or stay inside an Effect fiber; do not add ambient instance context shims.
+We are moving to V2, which is split across the `core`, `tui`, and `cli` packages. It is okay to read code in this package to understand how V1 worked, but do not make changes here unless explicitly instructed.
