Yogurt WangandClaude Opus 5.5 e02801d7f6 feat: stable-diffusion.cpp native API provider, node and Extra settings 
Add support for the native /sdcpp/v1 API of stable-diffusion.cpp's
sd-server (issue #4):

- Provider: stable-diffusion.cpp (default http://127.0.0.1:1234, API key
  optional for reverse proxies) and a "stable-diffusion.cpp" generation
  node using whatever model the server has loaded.
- Async jobs: submit to /sdcpp/v1/img_gen, poll jobs/{id}, and cancel the
  server-side job when ComfyUI interrupts or task_timeout is reached.
- "stable-diffusion.cpp Extra" node wired through a new extra_params input:
  negative prompt, steps (capped at 100 like sd-server), cfg, sampler,
  scheduler, distilled guidance, LoRA, init image + mask + strength,
  ControlNet, IP-Adapter, clip skip, eta, flow shift, hires fix, VAE tiling
  and cache mode. Port values merge under the node's extra JSON, and
  connecting it to another provider fails with a clear error.
- Framework: ExtraNode base, FamilySpec.extra_input, mask params,
  key_optional connections; parse_extra moves into the framework.
- Example workflow, Colab notebook for running sd-server remotely, tests.
