Subject: Replace Python plugins with native C++ .so, remove bundled Python
 (~95MB)

- Add native plugins: form43_checker, script_extender_checker, preview_dds,
  basic_games (75 game defs via IPluginProxy pattern with Steam/GOG detection)
- Remove portable Python from Dockerfile and build-inner.sh
- Add Python settings tab with venv support (system python3 + PyQt6)
- Skip loading plugin_python.so when Python disabled (default: off)
- Update pythonrunner.cpp to use venv at ~/.local/share/fluorine/python-venv/
- Preserve real file permissions in FUSE VFS (fixes native executable +x bits)
- Add FUSE_SET_ATTR_MODE handler so chmod works through VFS
- Fix desktop shortcut Exec= to use fluorine-manager launcher, not bare binary
