docs: frank-large halogen runbook, AGENTS.md + indices for the swap

New runbook frank-large-halogen27b-dflash2.md; LLM + vault indices
re-pointed, ROCmFPX q6agent runbook marked RETIRED (rollback target);
AGENTS.md topology row, detail section, image-capability paragraph
(two endpoints accept images now), bench-law prose and runbook index
updated.
