Build and Push Docker Container / build-and-push (push) Successful in 2m3s
- Add a private SSE endpoint that emits file change events for authenticated clients. - Replace the watch sleep loop with watchdog local file events and remote SSE triggers. - Debounce local event bursts and keep watch running after transient sync failures. - Add watchdog as a standalone CLI dependency and cover watch behavior in tests. - Bump NanoShare to 1.25.0 and the standalone CLI to 0.4.0.
