fix(ci): research promote tool inventory + 0023 upgrade seed bookkeeping (#2329)

## Summary
- Heartbeat customTools inventory includes `fn_research_promote_finding`
(64 tools).
- Schema-applier bookkeeping for migration `0023` research feature
provenance.
- Seed upgrade fixtures include `mission_features.slice_id` for the
unique index.

## Evidence
- Full greens earlier this session: **29662309385** (#2323),
**29663526777** (#2325), **29664692957** (#2327).
- Tip red after FN-8297: heartbeat 63→64 + schema upgrade seed.

## Test plan
- [x] heartbeat expected-tools + schema upgrade tests green locally
- [ ] Full Suite all shards green on tip after merge
