feat(cowork-service): scaffold Fastify bridge + seed clawcowork feature flags (H.1 + H.2)

H.1: Product registration
- Added 12 clawcowork feature flags to platform-service flags/seed.ts
  (sandbox, plugins, mcp, scheduling, computer_use, parallel_agents,
   marketplace, wasm, llm_multi_model, audit, platform_auth, dispatch_api)

H.2: cowork-service scaffold (services/cowork-service/)
- @lysnrai/cowork-service on port 4009, productId clawcowork
- createServiceApp + startService from @bytelyst/fastify-core
- Modules: health (dependency check), tasks (submit/list/get/cancel)
- Zod-validated config, Swagger, readiness endpoint
- 8 tests passing (1 bootstrap + 7 task routes), typecheck clean
