Every work-record type carried a stable identifier except tasks, whose rows held
only id, workplan_id, title, status and priority — nothing connecting a row to
CUST-WP-0067-T01 in the file it came from. Matching was therefore by title, so a
renamed heading looked like one task vanishing and another appearing, and the
forge-derived reset had to refuse to touch tasks at all.
Adds tasks.record_id (nullable: no migration can invent an identity for an
existing row) and a backfill that reads the pairing from the repository files,
where a task declares both its canonical id and its projection UUID. 5516 pairs
across 121 repositories with zero conflicts; 4456 of 6073 cache task rows
identified.
Diff and reset now key on record_id where present, falling back to a
title-prefixed key so an unidentified row stays visibly unidentified.
Unknown stays unknown: a row the files do not claim keeps no identity and the
reset keeps refusing to act on it, and an existing identity is never
overwritten — a mismatch is recorded as a conflict rather than resolved.
