Replaces the NestJS mana-search service with a Go implementation for
lower resource usage and faster startup. All 7 API endpoints are 1:1
compatible (search, extract, bulk extract, engines, health, metrics,
cache clear). Uses go-readability for content extraction and
html-to-markdown for Markdown conversion. Redis cache with graceful
degradation, Prometheus metrics, and structured JSON logging.
Binary: 22 MB vs ~200+ MB node_modules.

- Add Swagger/OpenAPI documentation at /docs endpoint
- Add admin module for system-wide API key management
- Add scheduler for monthly credit reset and usage cleanup
- Add Docker Compose entry for Mac Mini deployment
- Document all endpoints with descriptions and examples
Implement custom NestJS API Gateway for mana-search, mana-stt, and mana-tts:
- API Key management with CRUD operations and key regeneration
- Redis-based sliding window rate limiting
- Credit-based billing with tier support (free, pro, enterprise)
- Usage tracking with daily aggregates
- Proxy services to backend microservices
- Prometheus metrics endpoint
- JWT auth for management API, API key auth for public API
Database schema uses separate `api_gateway` schema in shared manacore DB.
