- Plugin: use bus.subscribeAll() Stream + forkScoped instead of callback facade
- Vcs: use bus.subscribe() Stream + forkScoped instead of acquireRelease callback
- Status: use bus.publish() Effect directly instead of Effect.promise wrapper
- Rewrite Vcs test to use facade functions (shared memoMap ensures singleton Bus)
- Add Bus integration tests for subscribe cleanup and instance disposal
