DSH crash-rescue plugin: undo config & plugin-code changes, secret-safe snapshots, one-click SAFE MODE, plus offline CLI/GUI that work even when DSH won't boot.

One header button stops running turns, goals and jobs, writes a plan to disk, and restores that work after a restart or crash; the button shape is the only status.

Purge Community Plus - DeepSeek Harness jailbreak plugin, adapted for DSH Desktop 0.2.1-rc.x. Fixes #119 host crash and the toolFilter preset-registration failure.
