FN-6783: recover orphaned task dirs into the task index
Reconcile on-disk task.json records that are missing from SQLite without resurrecting tombstoned IDs.
- Add TaskStore orphaned task directory scanning with metadata validation, FTS-safe insertion, cache updates, lifecycle events, and run-audit entries.
- Run the reconcile during store init and self-healing maintenance for tasks created after startup.
- Cover recovery, skip, and maintenance behavior with core and engine regression tests.
- Document task index reconciliation and add the published package changeset.
