Fix PATH issue on Steam Deck by using adaptive symlink locations

- Detect Steam Deck via /etc/os-release and use ~/.local/bin for symlinks
- Fall back to /usr/local/bin on other systems to avoid read-only filesystem
- Ensure target directories exist with mkdir -p before creating symlinks
- Keep profile.d approach as fallback and source for immediate availability
- Update uninstall script to clean up symlinks from both possible locations
- Use rm -rf for systemd override directory and specific file removal

Fixes #38
