- Detect ENOSPC errors via exit code 228/23 and log patterns (ENOSPC, no space left on device, Disk quota exceeded, errno -28)
- Add is_disk_full detection in exit-1 subclassification block for generic failures caused by disk space
- Show informational hint with current disk size when ENOSPC is detected
- Add recovery menu option to rebuild container with doubled disk size (up to 2 retries)
