Capture fresh high-energy benchmark evidence in the restart handoff

Update the handoff and changelog with the newly finished capped FMA high_energy result so the next session starts from current evidence instead of stale partials.

Constraint: Benchmark is still running overall and only partial strategies are complete
Rejected: Wait for repeated_section_aware to finish before updating handoff | Risks another stale restart gap
Confidence: high
Scope-risk: narrow
Directive: Replace the partial cap16 table with the final ranking once repeated_section_aware and report.json land
Tested: Verified /tmp/ab_smoke_seg_cap16/high_energy/fma_reports_smoke/eval.json; verified docs now record high_energy = 12 / 1.0 / 1.0
Not-tested: Final cap16 multi-strategy report because repeated_section_aware is still in progress
