The tracker-mapping worker clears mapping_requested_at at claim time, so
a crash or hard failure between Process phases left the pattern dequeued,
unmapped, and with nothing to re-trigger it. Only an incidental sibling
remap could rescue it, so a lone pattern could stay stranded forever.
Implement the worker.StaleRecoverer interface, mirroring the enrichment
worker. ResetStaleMappings re-arms rows that were claimed but never
assigned a catalog row (common_tracker_pattern_id IS NULL) once idle past
a configurable window; a successful Process always assigns one via the
unmatched fallback, so the predicate cleanly detects interrupted runs and
self-heals after a single pass. ClearMappingRequestedAt now bumps
updated_at so the stale clock starts at claim time and the sweep never
recycles an in-flight claim.
Plumb a StaleAfter knob (default 600s) through the config struct, builder
env var, probod wiring, and Helm templates.

Every PromoteSource caller already loaded the tracker pattern under
the same transaction, so a dedicated single-column UPDATE only
duplicated machinery and forced callers to learn a second mutation
verb. Add `source = @source` to Update's SET clause, mutate
Source/UpdatedAt on the receiver, and call Update at the three
promotion sites (worker merge loop, worker adoption loop, and
reportDetectedTracker). The shouldPromoteSource gate still ranks the
candidate against the loaded value; Update is now the single write
path that can advance source, with a doc comment spelling out the
load-first contract.
Re-cast the coredata tests around Update: WritesSource pins the
round-trip from receiver to DB, NotFoundForMissingRow preserves the
ErrResourceNotFound contract callers rely on. The old
OnlyTouchesSourceAndUpdatedAt test was a property of the narrow
PromoteSource UPDATE and no longer applies — Update intentionally
rewrites the full editable column set from the receiver.
