* Harden layout validation, watcher lifecycle, and connection robustness
- Throw instead of silently skipping when the packaged daemon-entry is
missing, preventing layout regressions from passing build checks.
- Terminate idle parcel-watcher processes to reclaim native handles and
avoid crash-prone native node module teardowns on shutdown.
- Bind the persisted WS fallback port first to prevent orphaning active
mobile pairings when the preferred port becomes free again.
- Cap concurrent disk reads for restored dirty tab verification at three
to prevent startup connection bottlenecks on remote SSH workspaces.
* Queue file IDs instead of snapshots in restored conflict scans
This avoids using stale file snapshots (e.g., outdated disk signatures)
if a tab is saved, closed, or re-baselined while waiting in the queue
behind the concurrency limit. The live state is now fetched from the
store and validated immediately before initiating the disk read.
