Remove AppImage build target and runtime references

We ship via portable tarball directory + .bin self-extracting installer
only; the AppImage path was unmaintained and pulling in linuxdeploy
tooling for a format we no longer publish.

Build:
- build.sh: drop appimage/all-includes-appimage modes (now: tarball,
  installer, all=both, shell). Output listing tracks the directory.
- docker/Dockerfile: drop BUILD_APPIMAGE arg and the linuxdeploy
  download/extract block.
- docker/build-inner.sh: drop build_appimage() (~120 lines), AppImage
  arm of the BUILD_MODE switch, *.AppImage summary listing.
- docker/AppRun.sh: deleted.
- .gitignore: drop *.AppImage / squashfs-root / *.flatpak entries.

Runtime: no longer key off APPIMAGE/APPDIR env vars or AppRun-set
state. The fluorine-manager launcher script already exports
FLUORINE_ORIG_*, MO2_BASE_DIR, MO2_PLUGINS_DIR, MO2_LIBS_DIR,
MO2_PYTHON_DIR for the same purpose, so simplify:
- envshortcut: appImageOrBinary -> launcherOrBinary; bundledFluorineIcon
  no longer probes APPDIR.
- nxmhandler: drop APPIMAGE-based wrapper path; use applicationFilePath.
- protonlauncher: rename cleanAppImageEnv -> cleanFluorineEnv, drop
  APPIMAGE/APPDIR/OWD/ARGV0/APPIMAGE_ORIGINAL_EXEC/DESKTOPINTEGRATION
  removals and .mount_Fluori pattern strip.
- prefixsetuprunner: same env-cleaning trim.
- utility, library.h, proxypython, mainwindow, moapplication, appconfig:
  comment cleanup pointing at the launcher instead of AppRun.
