Every "can't be together" rule now returns a reason instead of refusing. The game page and the install dialog show it with "Install anyway" / "Cancel", the confirmation is stored in the install record until the selection changes, and a warning stays on the game. Settings defaults and the method picks still never choose a clashing set.

• NR add-ons: NrAddons.Conflict(s), Installer.Conflicts; the Settings checkbox and AllowSeveralNrAddons are gone (old settings files still load). The installer no longer displaces add-ons it installs in the same run.
• MFG: OptiScaler's built-in unlock next to the MFG Unlock add-on is a conflict. By default [DLSSG] AdaMfgUnlock and AmpereMfgUnlock are written as false; a user value still wins and then shows the warning. Keys taken from the OptiScaler.ini of janblade F5 v0.1.32 (both shipped as false).
• Anti-cheat (row 20) and writable Store folders: methods stay listed with a warning and auto never picks them. A locked folder (write probe fails) still blocks.

Verified: build -warnaserror and the full suite (601 tests) pass locally. Screens to check: game page (works-in-this-game list, warning bar under the mods, ShortFuse + Lecram pair), the "Check before installing" dialog, Settings > defaults (checkbox removed).
