refactor: add pattern utils and split api.ts into modules
1. Pattern Detection Utility (src/utils/patterns.ts) - Centralize tool category patterns (domain, deposit, server, etc.) - Add memory category patterns (company, tech, role) - Add region detection (korea, japan, singapore, us) - Add tech stack detection (postgres, redis, nodejs, etc.) - Export detectToolCategories(), detectRegion(), detectTechStack() 2. API Route Modularization (src/routes/api/) - deposit.ts: /balance, /deduct with apiKeyAuth middleware - chat.ts: /test, /chat with session handling - contact.ts: Contact form with CORS middleware - metrics.ts: Circuit Breaker status endpoint 3. Updates - tools/index.ts: Use detectToolCategories from patterns.ts - api.ts: Compose sub-routers (899 → 53 lines, 94% reduction) Benefits: - Single source of truth for patterns - Better code organization - Easier maintenance and testing Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Centralized pattern detection for keyword matching

* - Tool category detection (tools/index.ts)
|

* - Memory category detection (openai-service.ts)
|

* - Region/tech stack detection (server-agent.ts)
