- Extract handleKeydown into useKeyboardShortcuts.ts composable; reduces
MainLayout by ~20 lines and isolates keyboard logic cleanly
- ConnectionTree: watch groups for additions and auto-expand new entries
- MonitorBar: generation counter prevents stale event listeners on rapid
tab switching
- NetworkScanner: revoke blob URL after CSV export click (memory leak)
- TransferProgress: implement the auto-expand/collapse watcher that was
only commented but never wired up
- FileTree: block binary/large file uploads with clear user error rather
than silently corrupting — backend sftp_write_file is text-only
