Record the first cap48 seed123 hybrid score for the multi-seed check

Persist the newly finished cap48 seed123 hybrid result so the second-seed validation run now has measured evidence instead of only a runtime checkpoint.

Constraint: seed123 high_energy and the final report are still pending
Rejected: Wait for the full seed123 report before updating docs | Would leave the multi-seed evidence stale across sessions
Confidence: high
Scope-risk: narrow
Directive: Replace the seed123 partial section with the final two-strategy ranking once high_energy eval and report.json land
Tested: Verified /tmp/ab_smoke_seg_cap48_top2_seed123/hybrid/fma_reports_smoke/eval.json; verified docs record hybrid=24/0.9583/1.0 and high_energy still in build-index
Not-tested: Final seed123 comparison because high_energy has not finished yet
