Refresh the second cap48 seed checkpoint now that hybrid reached evaluation

Update the handoff and changelog with the newer seed123 runtime milestone so later sessions know the hybrid lane has advanced from build-index into capped evaluation.

Constraint: No measured seed123 score is available yet, only a later execution milestone
Rejected: Leave the older build-index note in place | Would make the restart handoff stale and less actionable
Confidence: high
Scope-risk: narrow
Directive: Replace the seed123 runtime note with measured scores as soon as hybrid eval.json or report.json land
Tested: Verified active seed123 hybrid evaluate.py process; verified docs now record seed123 current phase as evaluate.py --max-queries 24
Not-tested: Seed123 strategy scores because hybrid eval.json has not landed yet
