fix(workplans): adopt ADR-007 derived identifiers for unregistered records

These workplans exist only in the retired local hub. Their random pre-ADR-007
identifiers are refused by C-06 as stale references, so they cannot be
registered. Deriving from the canonical record id takes no identity from
anything: central does not hold them and the old ids die with the cache.

Records central already holds were deliberately left untouched.

 Prototype re-ingest/re-fingerprint recovery primitives and a discovery hook
 interface (no network coupling baked into the core).
