- Add provideInstance, provideTmpdirInstance to test/fixture/fixture.ts
- Delete test/fixture/instance.ts (withServices no longer needed)
- Rewrite format tests to use provideTmpdirInstance + testEffect (fully Effect-native)
- Effect-native bus tests use provideTmpdirInstance
- Replace manual subscription Map with PubSub.unbounded per instance
- Per-type PubSubs + wildcard PubSub, cleaned up via addFinalizer
- InstanceDisposed published before PubSub shutdown so subscribers see it
- Add makeRuntime to run-service.ts (single runtime with runPromise + runFork)
- Legacy facade preserved: publish/subscribe/subscribeAll same signatures
- subscribe/subscribeAll fork stream consumer fibers, return interrupt function
- Extract Format.file() for explicit formatting, remove event-driven subscription
- Inline Format.file() calls in write/edit/apply_patch tools
- Drop Bus.once (zero callers)
- Keep makeRunPromise as deprecated wrapper for existing services
