V315 -- BG2EE v2.7.3.0 -- UI Escape through death / cutscene + no manual pause

INSTALL:
1. Close BaldurII.exe and InfinityLoader.exe.
2. Extract this archive, open the All Editors folder.
3. Run SETUP_IN_GAME_ACCOUNTS.bat, choose the same BG2 game folder and Baldur.lua profile as before, then INSTALL V315.
4. Launch BaldurII.exe (or InfinityLoader.exe if your other mods need EEex).

V315 BEHAVIOR:
- Pressing Escape on the native WORLD_DEATH overlay requests the standard in-game Options menu instead of being ignored.
- Escape on the active world action bar also requests the normal Options panel, including in cutscene moments that still dispatch UI hotkeys.
- After a death, the native sidebar route is attempted first, then the regular Options engine as a fallback if the sidebar route is blocked. The death panel stays on the stack so death behavior is unchanged when returning from Options.
- Clock-click manual pause is disabled.
- The manual Pause keyboard action is intercepted while the world or death UI is accepting keyboard input.
- Scripted/engine hard pauses are not intentionally removed. Some truly hard-blocked cinematics may suppress all UI key events; these still require a live engine test.
- This is DEATH-STATE MENU ACCESS; it does not grant character invulnerability or change BG2 death mechanics.

UNCHANGED:
- V313 host-player-leaves => other players return to main UI.
- V314 safe world/router pulse and account/session login flags.
- Character files, names, exports/imports, slot ownership, folders, campaigns.
- Existing save/load restrictions. No automatic character backups.

Static validation: 15/15 focused V314/V315 regression tests passed.
Windows in-game check still required: test Escape (a) normally, (b) while dead, (c) in a cinematic that permits UI keys; test clock click and Pause/Space while in gameplay, then check Quit Party -> main UI and host/client disconnection.
