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).
