Revert frank-default-large to CIRU runtime (DFlash2 too slow)

Restore the CIRU ROCmFPX setup that DFlash2 replaced:

- Restore jcbtc/Qwen3.8-27B-CIRU-ActiveFPX-PromptForge v2 runtime
  (native depth-4 MTP, PromptForge DualView, ROCm 7.15)
- Archive the DFlash2 Vulkan deployment files in .AGENTTRASH
- DFlash2 was retired the same day it shipped (2026-08-21) for speed
- Revert docs (deployment.md, index.md, AGENTS.md); mark dflash2 page archived
- Restored scripts are byte-identical to the pre-swap CIRU versions
