feat: injectable application host (APPLICATION_HOST token) - #129
Conversation
…oken Register the running DanetApplication in the injector under the public APPLICATION_HOST token (constructor + re-assert at init start, most recently initialized app wins), so injectables and module lifecycle hooks can reach the app and its Hono router without an external reference. NestJS HttpAdapterHost analogue; unblocks forRoot-style extension modules such as @danet/graphql.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds a globally injectable application host, but it currently updates that host during construction as well as initialization. Creating a second application before initializing it can make consumers receive an uninitialized host, creating a concrete integration risk; merge should wait for the lifecycle behavior to be corrected or explicitly accepted. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

| See proposal.md. Modeled on NestJS's `HttpAdapterHost`: `@nestjs/graphql`'s `GraphQLModule` constructor-injects the host and its `onModuleInit` hook mounts the endpoint on the underlying server. In Danet the analogous pieces are token-based value providers (`@Inject('token')`), the `app.router` Hono getter, and the `OnAppBootstrap` hook that `init()` fires after `bootstrap()` completes (`src/app.ts:235-241`). The missing piece is only the registration of the application itself. | |||

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Close the application in a finally block.
The route test calls await app.close() only after fetch() and the assertion. If either operation fails, the listening server remains open and can leak resources into later tests. Wrap initialization, listening, fetching, and assertions in try/finally.
As per coding guidelines: spec/**/*.test.ts tests must use app.listen(0) and always await app.close() for cleanup.
