chore(packages): bump llama-cpp, llama-swap, and stable-diffusion-cpp

- llama-cpp: 9496 -> 9802
- llama-swap: 216 -> 230; UI embed moved upstream to internal/server/,
  skip forking tests that exec /bin/bash (unavailable in the sandbox)
- stable-diffusion-cpp: 462 -> 721; drop lora_enable.patch and
  server_mask.patch now merged upstream
