Summary

Three constructor parameters were missing explicit @Inject() decorators. Since tsx/esbuild doesn't support emitDecoratorMetadata, NestJS couldn't resolve them, causing the DI container to hang forever during onModuleInit with no error output.

Fixed:

SummarizationService: @Inject(EmbeddingService)
CronService: @Inject(SummarizationService)
SkillsController: @Inject(SkillsService)

Also includes the dotenv fix (PR #108) for loading .env from monorepo root.

Test plan

pnpm --filter @mosaic/gateway exec tsx src/main.ts → Gateway

tsx/esbuild doesn't support emitDecoratorMetadata, so NestJS can't
infer constructor parameter types at runtime. Three services were
missing explicit @Inject() decorators:

- SummarizationService: EmbeddingService parameter
- CronService: SummarizationService parameter
- SkillsController: SkillsService parameter

Without these, NestJS DI hangs forever during onModuleInit resolution
with no error output — the process silently exits (or hangs with a
keepAlive).
