[EMERGENCY HOTFIX] Stable - 1.82.23 Sophon Incident (#739)
# Main Goal As per May 5th 2025 (on Genshin Impact 5.6 update), HoYo just removed the entire Zip packages from the launcher APIs. causing a major issue throughout Third-party Launcher Community (Collapse is no exception). This PR also fixed some essential features which has stopped working due its dependency on Zip's ScatteredFiles references. Now, all those features are moving its dependency entirely to Sophon as its game files references. # What's changed? - **[Fix - Genshin Impact]** Infinite Loop/Getting Stuck while Updating Game to 5.6.0 - **[Fix - Genshin Impact]** Crash on File Cleanup feature due to missing Zip's pkg_version ScatteredFiles reference. - **[Fix - Genshin Impact]** Crash on Game Repair feature due to missing Zip's pkg_version ScatteredFiles reference. - **[Fix]** Possible crash when user defines ``version`` field in ``config.ini`` with 2-numbers or less format. - **[Fix]** [#736](#736) GameIniVersion ignores mismatched value # Note These changes were backported from the ``main`` branch manually.
