FNXC:PostgresCutover 2026-07-05-13:00:
Ported from a hand-rolled node:sqlite INSERT OR IGNORE into fusion.db to the
store's own FN-6783 orphaned-task-dir reconcile (TaskStore.reconcileOrphanedTaskDirs),
which non-destructively re-imports valid live task directories that have no
task row anywhere — including soft-deleted/archived/tombstoned ID preservation
that the old raw INSERT could not honor. The script boots the backend, runs the
reconcile with the recency window disabled, and reports each requested ID.
