Fix CLI process exit so `fn agent stop`/`fn agent start` no longer hang up to 60s and eventually time out on repeated retries against the same agent.
- Root cause: `resolveProject()` cached an unclosed `TaskStore`, and `createAgentStore()` never closed the `AgentStore` it opened, leaving SQLite handles alive after the command's real work was done.
- Add `resolveProjectPathOnly`/`closeProjectStore` helpers in `project-context.ts` so path-only callers never leak a `TaskStore`.
- Explicitly close `AgentStore` on every exit/return path in `agent.ts`, since `process.exit()` skips pending `finally` blocks.
- Add a bounded fast-fail timeout around the state-store write (default 10s, overridable via `FUSION_AGENT_CMD_TIMEOUT_MS`) so a genuinely stuck operation fails fast with a clear error and non-zero exit instead of hanging.
- Add regression tests covering process-exit/store-closing behavior and update CLI reference docs.
- Add changeset for the patch release.
