feat: swap both LLM services + remove config-assertion tests

Dankserver (frank-default-small):
- Stock llama.cpp (latest master, CUDA build) replaces ik_llama.cpp
- Model: peculiar-ragdoll/Tiel-Coder-35B-A3B UD-Q6_K_XL (30 GB)
  Architecture: qwen35moe, 40 layers (10 attn + 30 SSM), 256 experts/8 used
- CTX_SIZE=200700 (66900/slot × 3 parallel), Q8_0 KV (~2 GB cache buffer)
- --cpu-moe for expert offload, -ngl 999 (non-expert on GPU)
- mmap enabled; removed ik_llama-specific flags

Dankclaw (frank-default-large):
- ROCmFPX fork with PR #27742 (qwen4exp arch) merged and built
  at /home/dank/GitPackages/ROCmFPX/build-qwen38
- Model: kingjones777/Qwen3.8-Flash-Next-ROCmFP4-STRIX_LEAN (98.5 GiB)
  Architecture: qwen4exp, 48 layers (12 attn + 36 SSM), 512 experts/10 used
  QSA indexer, hyper-connections, PLE, Q4_0_ROCMFP4 quant
- CTX_SIZE=131072 (128k) × 1 parallel, f16 KV
- --fit off (auto-fit segfaults on qwen4exp hyper-connection config)
- Removed MTP draft, mmproj; kept Qwen-Sharp chat template + reasoning

Tests:
- Removed tests/frank_small_config.bats and tests/frank_large_config.bats
  (moved to .AGENTTRASH/). These were config-assertion tests that checked
  'is variable X set to Y' rather than testing the serve script's actual
  behavior. All 199 remaining tests pass.
- Updated test-changed.sh mappings and changed_tests.bats to reflect the
  removal.
