Stops the execute → pause-abort → re-queue-to-todo infinite loop for tasks whose implementation work is done but a dependency/blockedBy blocker is still live, by diverting them into a dedicated parked state instead of feeding the FN-7863 no-progress backstop or looping forever.
- Add TaskExecutor.parkCompletedBlockedTask(): when work is complete but getTaskCompletionBlocker() still reports a blocker, park the task in todo with pausedReason:"completed-work-blocked", status:"queued", preserved worktree/branch/steps, and a cleared execute-requeue signature.
- Replace shouldFinalizeCompletedTask's boolean with getCompletedTaskFinalizationDecision() returning "finalize" | "blocked" | "incomplete" so both the paused-after-completion and finalization call sites can react to the new "blocked" outcome without re-entering execution.
- Divert completed-but-blocked tasks before the FN-7863 execute-requeue-loop counter increments, so waiting-on-dependency states are no longer misclassified as EXECUTION_DISPATCH_LOOP_EXHAUSTED.
- Add SelfHealingManager.reconcileCompletedBlockedTasks(): a bounded sweep (wired into both startup/maintenance and periodic self-healing passes) that clears the park and advances the task to review once getTaskCompletionBlockerForStore() resolves, guarded by auto-merge eligibility, user-pause, and live-execution checks; failed advances re-park rather than strand the row.
- Add run-audit mutation types task:completed-blocked-parked and task:completed-blocked-advanced (ids/counts/outcomes-only metadata) plus AGENTS.md/docs/architecture.md entries documenting the new lifecycle.
- Extend execute-requeue-loop-guard.test.ts with coverage for the park/advance flow, including the zero-step task edge case.
