Add Python init diagnostics, AppImage build system, misc Linux fixes

- python: switch Py_InitializeEx → Py_InitializeFromConfig for explicit
  error reporting; add dladdr + fprintf diagnostics to trace which DSO
  Python symbols resolve to and whether Py_IsInitialized succeeds
- python: log RTLD_NOLOAD vs fresh-load outcome when promoting libpython
  to RTLD_GLOBAL
- build: add Docker-based AppImage build script (build.sh), update
  Dockerfile and build-inner.sh for AppImage-only workflow
- build: remove Flatpak support entirely; move AppImage metadata
  (desktop/metainfo/icon) from flatpak/ to data/
- Add Monster Hunter Wilds basic_games plugin
- .gitignore: exclude squashfs-root, build-source, flatpak-repo,
  __pycache__, fomod-plus-settings.ini
- Various Linux port fixes across wineprefix, processrunner, proton
  launcher, FUSE connector, instance manager, download manager,
  sanitychecks, and NaK Rust paths/runtime_wrap
