refactor: Extract api-server.ts routes into 6 modular route files

api-server.ts reduced from 3089 → 449 lines (85% reduction).
All 71 route handlers extracted into focused modules:

- routes/governance.ts: 8 governance endpoints
- routes/commands.ts: command execution + EXECUTABLE_COMMANDS
- routes/workers.ts: 11 worker pool endpoints
- routes/runspaces.ts: 10 runspace CRUD/lifecycle endpoints
- routes/features.ts: vision, MCP, state, agents, architecture, YOLO, auth
- routes/forge.ts: init, feedback, compliance, errors, diffs, health

Shared infrastructure:
- route-context.ts: RouteContext interface for dependency injection
- middleware.ts: rate limiting, validation schemas

Also removes 2 remaining as-any casts in App.tsx and dashboard-live.tsx.

Verified: tsc clean, 64 test files pass (1953 tests), real server
tested with curl against all major endpoints (Rule 0).
