Add comprehensive daemon RPC integration tests (bd-117)

- Add TestDaemonRPCServerIntegration for basic RPC integration
- Add TestDaemonConcurrentOperations for concurrent client tests
- Add TestDaemonSocketCleanupOnShutdown for socket cleanup verification
- Add TestDaemonServerStartFailureSocketExists for socket conflict handling
- Add TestDaemonGracefulShutdown for graceful shutdown verification
- Use /tmp directly to avoid macOS socket path length limits (104 chars)
- Add mockDaemonServer with ready signaling to avoid race conditions
