- Add simctl availability check before attempting cleanup
- Capture and analyze error output for better diagnostics
- Implement fallback: manual deletion when simctl fails
- Provide specific error hints (permission, in-use, service issues)
- Skip early when no unavailable simulators exist
- Show partial success status when some deletions fail
Error scenarios now handled:
- simctl not available → skip with friendly message
- Permission denied → show hint and try manual deletion
- Device in use → show hint and try manual deletion
- CoreSimulator service issues → show hint
- Partial failures → show "partially cleaned X/Y"
Fixes#520
