Move undocumented flaky engine tests into the formal quarantine path.
- add quarantine ledger entries for flaky engine test files observed under concurrent/full-suite load
- exclude the quarantined engine test files from vitest projects so they no longer run in gate and reliability pools
- remove the undocumented it.skip markers by quarantining at the file/config level instead

Update @earendil-works/pi-coding-agent and @earendil-works/pi-ai from
^0.78.0 to ^0.79.1 across cli, engine, and dashboard. This brings in
Claude Fable 5 (claude-fable-5) on the Anthropic and Amazon Bedrock
providers.
Fusion's model picker is registry-driven (/api/models -> pi ModelRegistry,
filtered by provider, not model id), so Fable surfaces automatically for
users with Anthropic or Claude CLI auth configured — no Fusion-side model
list change needed.
Verified: all core packages typecheck clean against 0.79.1; boot smoke
(fn --help, /api/health 200, clean shutdown) passes.

Guarantee AI merge clean-room worktrees are pruned on merge completion and swept by task state.
- prune pre-existing same-task AI merge temp worktrees before starting a new merge and audit cleanup outcomes
- add task-aware tempdir sweep rules with a short grace period for done or archived tasks and immediate cleanup for deleted tasks
- extend merger and self-healing coverage and document the updated stale worktree policy

Stop the self-healing DB corruption test from leaking into unrelated tmpdir state while quarantining the known flake.
- mock node:os tmpdir usage so the test runs inside a per-test sandbox and cleans it up after each case
- add the flaky self-healing DB corruption test to the engine default exclude list
- record the quarantine entry and failure context in scripts/lib/test-quarantine.json

Keep AI merge commit finalization running when the task disappears during settings resolution.
- fall back to a synthetic task stub before merging effective settings in runAiAgentForCommit
- add an engine regression test covering deleted-task settings degradation
- add a patch changeset for the published CLI package

Prevent rebuilt dashboard tabs from reusing stale cached assets after a deploy.
- revalidate service-worker asset requests against the network before falling back to cache and bump the cache version
- suppress repeated version-change reloads for the same remote build and cover the new behavior with dashboard tests
- update engine heartbeat test expectations for summarized task creation metadata and add the published package changeset

Update the skill diagnostics test to assert against the structured logger surface that now emits the diagnostics output.
- spy on [1mpiLog.log[22m instead of [1mpiLog.warn[22m in the structured logger diagnostics test
- keep the existing [skills] and [executor] assertions while matching the current logging path

Treat already-finalized or paused workflow-graph exits as benign instead of failure-worthy.
- log info-level benign messages when workflow graph runs end after a task is paused or has already advanced out of in-progress
- keep true in-progress graph failures on the existing failed-and-handoff path with failure logging
- add executor recovery coverage for todo, in-review, done, paused, and genuine failure cases
- add a patch changeset for the published CLI package

Ensure agent-created untitled tasks still request AI-generated titles even when project auto-summarization is disabled.
- force summarize=true for agent-created tasks that do not provide an explicit title
- add engine tests covering untitled, titled, and title-generation behavior with autoSummarizeTitles disabled
- document the agent-task summarization behavior in settings docs

Suppress legacy stalledReview hydration for tasks already owned by the merge queue and avoid repeated mergeable-review re-enqueue churn for queued tasks.
Fusion-Task-Id: FN-6088
Treat persisted merge queue ownership as an active merge-lane owner when hydrating in-review stall state and when self-healing scans for ghost, stalled, or completion-handoff-limbo tasks.
Also clear false completion-handoff exhaustion for tasks that are still owned by the merge queue so previously poisoned review tasks can continue merging.

Treat previously recorded unlinked-mission advisories as authoritative across insight states.
- remove the generated-only insight filter when checking for an existing unlinked mission advisory
- suppress duplicate advisories even when the existing insight is dismissed, archived, or confirmed

Ensure limbo recovery attempts count only when auto-merge requeue is actually accepted.
- require completion-handoff recovery to enqueue merge work and confirm the requeue callback accepted the handoff before incrementing recovery counters
- return a boolean from the in-process runtime auto-merge requeue hook so self-healing can distinguish accepted versus rejected handoffs
- add coverage for rejected requeues, accepted retries, exhaustion behavior, and stalled in-review tasks that should not be deadlocked by rejected limbo recoveries
