## Summary
Main Full Suite shards have been red after recent landings. Root causes:
1. **Executor tests** — `execute()` now polls
`getTaskVerificationRequestAsync` (chat-enqueued verification). Shared
`createMockStore()` (and soft-delete inline store) lacked the method, so
nearly every execute-path suite failed with `is not a function`.
2. **TaskDetailModal suites** — `NativeStructurePreview` imports `Map` /
`Lightbulb` / `BarChart3` / `Target` / `CircleAlert` from lucide; the
shared TaskDetail lucide mock omitted them, so suites failed at import.
3. **Grok process-lifecycle** — 15s bound stress timed out under
full-suite load without product-bug evidence → quarantined on sight per
AGENTS.md.
## Test plan
- [x] `executor-task-done-blocked`, `executor-fast-mode-workflows`,
concurrent-execute race
- [x] `executor-step-session`, plan-only scope leak, review-step
indexing
- [x] `TaskDetailModal.create-pr` + `TaskDetail.mobile-transition`
- [ ] Full Suite CI on this PR

## Summary by CodeRabbit
* **Improvements**
* Added `html2canvas` support in the dashboard to enable HTML-to-canvas
rendering needed for visual structure previews.
* **Tests**
* Updated task execution test mocks to handle task verification-request
flows reliably.
* Improved task deletion safeguard coverage and related execution
behavior checks.
* Enhanced test stubs to support structure preview rendering elements
during modal-related tests.
* **Chores**
* Quarantined a timing-sensitive process lifecycle test and refreshed
quarantine tracking to improve full-suite stability.
