Fixes regression from #18546 and #18679. ## Problem The is_from_yml ISO branch constructed iso_archive unconditionally, bypassing the cache check inside add_game, making the cache write-only for yml-sourced ISOs. ## Fix Added a lightweight index cache entry (iso_path + "//index") storing the subdir list + mtime. On hit, skips archive construction entirely. On miss, walks as before and writes the index
