feat: Effect services + HttpApi implementation + kit entry/CLI/dev server

- RomConfig/RomCache on the kit's ConfigService/CacheStore; RomSync wires the
  pure domain into the kit SyncEngine (poll/watch/coalesce/fingerprint) and
  ProviderClient; EngineStatus assembly shared by REST + SSE
- makeApi: HttpApiBuilder groups over live service values (handler runtime
  shares the plugin runtime's singletons) + sseRoute status feed
- index.ts: definePluginKit entry (async-main boundary); headless-first (UI
  serve failure logged, engine continues)
- cli.ts on the kit dispatcher: scan/detect/preview offline, sync/uninstall
  online; set-password is gone with the standalone server
- dev.ts: auth-free loopback API server (:5885) — the dev:live proxy target;
  never bundled
- verified live host-less: raw config round-trip on disk, status/platforms/
  preview endpoints, soft-fail reconcile without a host
- CI: workspace install, per-package typecheck, publish from plugin/
