refactor: MAGATAMA pipeline code quality audit — all functions <50 lines

Complete code quality audit of llm-gateway pipeline modules for MAGATAMA standard compliance (50-line function maximum). All pipeline functions refactored to ensure high cohesion and readability.

Pipeline module compliance (verified):
✅ llm-client.ts — Refactored callOllama() (58→26 lines) via helper extraction
✅ instrumented-llm-client.ts — All functions <50 lines (wrapper layer)
✅ router.ts — Refactored routeByScore() (81→32 lines) via delegation
✅ request-scorer.ts — 870-line file, all functions <50 lines
✅ external-providers.ts — All functions <50 lines (49-line max)
✅ post-validator.ts — All validators <50 lines

Verified:
✓ npm run build (TypeScript, zero errors)
✓ All 6 pipeline modules independently audited
✓ Production-ready for Erik deployment (PM2 ids 19+20, port 3103)
