Phase 9 R1c: daemon wiring + integration test

- Wire RpcRouter::with_repo_root at daemon startup in services.rs
  using <blob_store_root>/repos. Nodes with no blob_store_root
  still return NotConfigured (unchanged).
- Add end-to-end ensure→cached→release integration test that seeds
  a bare git repo in a tempdir and exercises the real git-clone
  path. Marked #[ignore] so CI runners without git skip silently;
  runs green locally.
