Fixed
- The Performance tab's system-mutating actions weren't serialized against each other, so "Restore All" could run while an "Apply" was still in flight and corrupt the reversible snapshot. Every Apply command (power plan, visual effects, Game Mode, Xbox Game Bar, GPU, processor state) plus Restore All, Trim RAM, Create Restore Point and Toggle Hibernation is async and awaits real system work (registry writes, powercfg, EmptyWorkingSet across all processes). Nothing prevented a second command from starting mid-flight: the snapshot's own SemaphoreSlim only guards the load-modify of the _snapshot field, not the full apply→revert sequence. In the worst case, pressing Restore All while an Apply's registry write was still running let Restore All null _snapshot and delete the persisted baseline, leaving a tweak applied with nothing left to revert it (and other tabs that mutate the same system state — Tweaks, Cleanup's SFC/DISM — could interleave too). Every one of these ten commands now acquires the app-wide OperationLockService SystemModification lock (the same lock SFC/DISM and the Environment Variables editor already use) right after its confirmation dialog; if another system-modification operation is running, the command reports "Cannot start — is already running." and bails before touching the system. Toggle-based commands re-sync their toggle from the live profile on that early return so the UI doesn't show a change that wasn't applied.
