docs: wrap up the 2026-09-19 fleet cutover

frank-large -> CIRU v4.4.1 Orca (new runbook), frank-medium -> the deployed
orcarouter Q8_0 / DFlash2 Q4_K_M / balanced 32:33 / 327680 state. The d374ab9
frank-medium deploy updated only scripts/tests and left AGENTS.md, the runbook
and both indexes on the predecessor (ajgazin Swift UD-Q8_K_XL, 35:30, 393216).

- AGENTS.md: frank-large section (CIRU Orca, root unit, runtime gate, PLE, MTP)
  + frank-medium section and topology row to the deployed shape
- new runbook frank-large-ciru-orca.md
- frank-medium runbook header/intro: orcarouter Q8_0 swap, 32:33, 327680;
  predecessor kept as calibration history
- LLM index.md: intro + mermaid (halogen->CIRU, GSQ-RCO->Gemma4, Swift->orcarouter),
  add ciru-orca, retire halogen
- top-level index.md: add ciru-orca link (docs-index seam), retire halogen,
  fix frank-medium entry
