Subject: Add Root Builder plugin, Linux game detection, and OMOD installer fix

- New native Root Builder plugin (src/plugins/rootbuilder.py) with copy
  and symlink deploy modes, auto-deploy hooks, backup/restore, and
  third-party conflict detection that moves incompatible plugins to
  DisabledPlugins/. In link mode, .exe/.dll are always copied to avoid
  Wine/Proton path resolution issues with symlinked executables.

- Fix basic_games detection on Linux: steam_utils now checks native
  Steam paths (~/.local/share/Steam, Flatpak, Snap), epic_utils uses
  correct Linux Heroic config paths, gog_utils falls back to Heroic
  GOG installed.json when Windows registry is unavailable.

- Fix OMOD installer crash: isArchiveSupported now handles both IFileTree
  (from mod list refresh) and string (from install check) arguments.

- Add flatpak manifest step to copy source-tree Python plugins
  (src/plugins/*.py) into the build output.
