fix: address CodeRabbit review comments

- Add path validation to /api/create-folder endpoint (forbidden system dirs)
- Fix repo name extraction to handle trailing slashes in URLs
- Add cleanup of partial clone directory on SSE clone failure
- Remove dead code branch (unreachable message)
- Fix Windows path separator detection in createNewFolder
- Replace alert() with setError() for consistent error handling
- Detect ssh:// URLs in addition to git@ for SSH key display
- Show create folder button for both workspace types
