95ec9ed7 - fix: Unblock `watch` loop so interruptible persistent tasks restart on file changes (#12509)

fix: Unblock `watch` loop so interruptible persistent tasks restart on file changes (#12509) ## Summary Fixes #12505 - **Cause**: The fire-and-forget change (PR #12449) moved a `TaskTracker` into a detached `tokio::spawn` for persistent tasks. Since persistent processes run forever, the tracker's `mpsc::Sender` clone is never dropped, which blocks `ExecutionTracker::finish()` indefinitely. This prevents `Run::run()` from returning, starving the watch loop of the ability to process any subsequent file-change events. - **Fix**: Use a no-op `TaskTracker` (throwaway channel) for fire-and-forget persistent tasks so the real execution tracker can complete. - **Observability**: Adds `debug!` traces at key decision points in the watch loop (event receipt, run processing, task stopping, run completion) to make future watch-mode issues diagnosable with `-vv`.
