DeepPurge v0.9.0: thorough, but contained first

[SysAdminDoc]

DeepPurge is a Windows uninstaller that goes deeper than the built-in one: it removes the program, then hunts down the leftovers, registry orphans, stray folders, scheduled tasks, and the cruft most uninstallers walk past. Currently v0.9.0.

The recent releases were almost entirely about containment, because a tool with deletion power has to be careful before it's thorough. The privileged helper now runs contained rather than with a blank check, scheduled-task execution got hardened, registry rollback is bound to real transactions so a failed cleanup can be undone, and Firefox extension removal got fenced off from touching more than it should.

That caution shows up on the roadmap too: the Install Monitor V2 replay is quarantined until its provenance can be trusted, and deletion policy is being centralized so every removal reports a success-only outcome you can audit rather than a fire-and-forget delete.

The thing I can't simulate is the sheer variety of installers in the wild. The thread pinned next to this one is for reporting apps that left junk behind after a purge, or the opposite and more urgent case: anything DeepPurge removed that it shouldn't have.
