Remaining Sneak and Pack Switching repair - October 12, 2026

This copy includes the second fixes for the two remaining problems:
- Toggle Sneak owns Minecraft's persistent-sneak bit while latched, restoring
  its previous native value on release, disable, focus/menu loss or resume.
- Pack Switching sets the outer Settings controller's reload-on-exit flag;
  the prior inner-controller override allowed editing but did not request reload.

Targets only Minecraft for Windows package 1.26.5203.0 (26.52), x64.
Exact initializer signature and native reload gate were checked in this build.
Build/policy tests do not establish these replacement fixes work in-game.

Close Minecraft and the old controller before starting this copy.
Use Start Client.bat, then activate the client after Minecraft opens.
Check a Shift tap/release and two visibly different global resource pack changes.
Return to the world after each pack change. Also check focus/menu and Off cleanup.
