Slice 2 of the CLI harness Effect migration. Drops the last raw Bun.spawn call sites in withCliFixture. - `serve` and `acp` both move from `Effect.acquireRelease(Bun.spawn(...))` to `appProc.spawn(ChildProcess.make(...))`. The spawner's built-in acquireRelease finalizer handles SIGTERM on scope close — no manual wiring needed. - `handle.stdout` / `handle.stderr` are already Effect Streams, so the `fromBunStream` helper is gone (Stream.fromReadableStream + the per-pipe error-tag boilerplate it wrapped). - acp's stdin moves from imperative `proc.stdin.write` + `proc.stdin.end` to a Queue<Uint8Array> fed into the spawner's stdin Sink via Stream.fromQueue. `send` is `Queue.offer`, `close` is `Queue.shutdown` — shutdown propagates as stdin EOF, which is ACP's graceful-exit signal. - ServeHandle/AcpHandle public shape: `kill`/`close` become Effect<void> and `exited` becomes Effect<number> (was () => void and Promise<number>). The platform error that cross-spawn-spawner raises on signal-kill is collapsed to exit code -1 so `exited` stays a clean Effect<number> — matches the test contract (just needs proof of exit). Two consuming tests updated to yield the Effect instead of awaiting the Promise.

Agents
OpenCode includes two built-in agents you can switch between with the Tab key.
- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.
