Replace the single Band total with two adjacent metric groups:
- Devlogic total: softbench, prosebench, psychbench, depthsweep
(all non-infra, non-scenario suites)
- Sysops total: infrabench + scenariobench
Each group independently shows geo-mean tok/s, total tokens, and
pass/fail counts. Scenariobench contributes per-observation
gen_tokens/wall rates to the sysops geo-mean.
Remove the server-config badge (e.g. 'llama.cpp DFlash spec-decode,
131k ctx, fa on') from the front-page card header. Label, quant, and
engine badges remain.
Migration drops the old total_* columns and adds devlogic_* and
sysops_* columns to session_summaries.
