fix(cli): address code review findings for uninstall command

- Add path traversal guard in uninstallOutputFolder (resolve + startsWith)
- Thread silent flag through to cleanupCopilotInstructions
- Trim text input before path.resolve in directory prompt
- DRY uninstall() by delegating to extracted helper methods
- Validate projectDir existence before probing for BMAD
- Use fs.rmdir instead of fs.remove in removeEmptyParents (race safety)
