1600TROUBLESHOOTING:
1601 Commands broken? lean-ctx-off (fixes current session)
1602 Permanent fix? lean-ctx uninstall (removes all hooks)
1603 Manual fix? Edit ~/.zshrc, remove the \"lean-ctx shell hook\" block
1604 Binary missing? Aliases auto-fallback to original commands (safe)
1605 Preview init? lean-ctx init --global --dry-run
