The merge adds a new self-healing recovery path for tasks stuck in `in-progress` limbo (no pending step updates but not marked done), hardening `resetTask` and `recoverInProgressLimboTasks` with proper worker binding cleanup, audit event coverage, and integration tests validating the invariant acros

Adds a reconcile script to recover leaked soft-deleted tasks, threads delete audit context through all callers, and records soft-delete audit events with archive column tracking across core/engine/cli/dashboard, with reliability backstop tests covering caller alignment.
Fusion-Task-Id: FN-5175
Implements in-flight abort for soft-deleted tasks across all three execution lanes: executor, merger, and triage now check for `deletedAt` before proceeding and emit `task:soft-delete-in-flight-abort` audits rather than continuing work on a deleted task. The 829-line addition is dominated by integra

The merge introduces an atomic review handoff seam in the core store (`packages/core/src/store.ts`) and migrates executor and self-healing transitions to use it, replacing the previous multi-step mutable-state handoff with a single transactional operation. Extensive reliability backstops and regress

Adds a per-machine singleton lock that engages in
ProjectEngineManager.createAndStart() before any engine subsystems
spin up. Two fn dashboard processes can no longer run engines for the
same project on the same host — previously they would share .fusion/
state and corrupt worktrees / task rows for in-process projects.
The guard combines two independent checks:
- A proper-lockfile file at <project>/.fusion/engine.lock with
stale-lock recovery (auto-released on process death).
- A loopback listener on a hashed per-project address — UDS on
POSIX, named pipe on Windows. Stale UDS files are probed and
unlinked before a retry bind.
Failures raise EngineAlreadyRunningError. Both guards are released
from stopAll() and pauseProject(); a release on engine.start()
failure lets retries re-acquire cleanly.

Implements deterministic followup deduplication for the project engine, routing eval and PR followups through a new `verification-followup-dedup` helper that excludes the parent task to prevent self-referential loops, with tests covering eval-followups, merge-error-recovery, PR comments, and the new

The doc was rewritten to cover "every task-creation path" (with an
explicit enumeration of surfaces) instead of the older "task creation
flows (including ...)" wording, and uses "best-effort and non-blocking"
instead of "Creation is best-effort and non-blocking". Update the
documentation contract test to match the current phrasing.

Completes FN-5153 by delivering the soft-delete verification gate with a new end-to-end test suite covering the full soft-delete lifecycle and a documentation matrix summarizing the gate behavior. Updates the dashboard test file and adds a brief entry to AGENTS.md to surface the new feature.

Adds a `lineage-unlink` flag to triage parent deletes (FN-5131), enabling the split-into-subtasks path to break parent-child lineage on deletion. The primary addition is a comprehensive new test covering that split scenario, with minor adjustments to two existing lineage-related test files.
