Establishes the open-source 'key Python API' for secure custom nodes:
- comfy_api/latest/_sdk.py: opaque typed refs (ImageRef/ModelRef/AssetRef...),
a brokered ctx surface (assets/progress/scratch/events/storage + stubs),
and a Providers registry (ExecutionBackend/CtxProvider/RefResolver) with
in-process DEFAULTS so OSS behaves exactly as today (a ref wraps the real
object; ctx is a passthrough; zero-copy, zero-overhead).
- load_overlay(): env-var (COMFY_OVERLAY_MODULE) path loader that lets a
separable, proprietary cloud overlay register isolated implementations at
the seam. Unset => pure OSS. Wired guarded into main.startup.
- comfy_api/v0_0_3: new API version exposing sdk; registered in version_list.
Nothing isolation-specific lives in OSS: this is the seam, not the engine.
* ComfyAPI Core v0.0.2
* Respond to PR feedback
* Fix Python 3.9 errors
* Fix missing backward compatibility proxy
* Reorganize types a bit
The input types, input impls, and utility types are now all available in
the versioned API. See the change in `comfy_extras/nodes_video.py` for
an example of their usage.
* Remove the need for `--generate-api-stubs`
* Fix generated stubs differing by Python version
* Fix ruff formatting issues
