feat(cli): add serve command — Hono HTTP API server

Adds `uncaged-workflow serve` command that exposes workflow data via a local HTTP API for the upcoming Web UI (RFC #118 Phase 1). Routes: - GET /healthz — health check - GET /api/workflows — list registered workflows - GET /api/workflows/:name — show workflow details - GET /api/workflows/:name/history — version history - GET /api/threads — list threads (optional ?workflow= filter) - GET /api/threads/running — list running threads - GET /api/threads/:id — show thread records (parsed JSONL) - GET /api/cas — list CAS hashes - GET /api/cas/:hash — get CAS content - POST /api/cas — store content, returns hash - DELETE /api/cas/:hash — remove CAS entry - POST /api/cas/gc — garbage collect Default: 127.0.0.1:7860, configurable via --port/-p and --host. Refs: #118
