fix(coding-agent/commit): force clean exit after omp commit finishes

The agentic commit pipeline (`omp commit`) wrote its commit and then sat
spinning on Ctrl+C because nothing in `Commit.run()` drained the lingering
event-loop handles: `installH2Fetch()` keeps idle HTTP/2 sockets warm to
the provider, the Settings autosave timer can still be armed, and the
AgentSession's extension/runner machinery holds onto async-job and OAuth
refresh state even after `session.dispose()` releases what it knows how
to. Mirror the `runPrintMode` exit path from `main.ts` by calling
`postmortem.quit(0)` once `runCommitCommand` resolves so the CLI returns
to the shell, runs registered cleanup callbacks, then exits — same model
the non-interactive launch flow already uses.

Also widens the private bash-tool helpers' `notices` parameter to
`readonly string[]` so `bun check:types` keeps passing — the public outer
arm already accepted `readonly string[]` and an upstream commit had only
partially propagated the change.

Fixes #1041
