Revert merge c118478805 relative to its first parent after the user confirmed the merge was requested in the wrong conversation. Remove the published Missions plugin, control routes, UI, playbooks and packaging references; do not rewrite dev history or touch durable-refactor work in the separate missions-v2 checkout.
Preserve subsequent PRs #792, #829 and #830. Remove only #829's now-invalid Mission reader import, dismissal hook and dedicated reader scenario, retaining the native questions/permissions dock, file-preview navigation and its other tests. Keep the 2.0.22 package pin and parent-session creation fence.
Validation: revert applied without conflicts; all 139 original merge paths reversed; later-only paths retained except the three minimal interruption-dock integration adaptations. Server and UI TypeScript checks and 18 automation/plugin lifecycle/desktop resource tests pass using existing local dependencies. Staged diff checks are clean. Full hosted CI, browser suites and native 2.0.22 qualification were not rerun for this immediate user-authorized admin revert.
