DiffusionCapabilities class

Capability descriptor for the loaded diffusion backend / model. Sources pre-IDL: Swift DiffusionCapabilities (OptionSet bit flags — supportsTextToImage, supportsImageToImage, supportsInpainting, supportsIntermediateImages, supportsSafetyChecker) Kotlin DiffusionTypes.kt:378 (DiffusionCapabilities, mirror of Swift) RN DiffusionTypes.ts:210 (interface with supportedVariants / supportedSchedulers / supportedModes / maxWidth / maxHeight / supportsIntermediateImages) Web — n/a C ABI rac_diffusion_types.h:352 (rac_diffusion_info_t — flags + max_width / max_height)

The IDL takes the RN-style "what can the backend do?" shape (lists of supported enums + a single max-resolution scalar) since it carries the most information; SDKs whose pre-IDL surface is a bit-flag set must map each flag to populating / leaving the corresponding repeated field. max_resolution_px represents the larger of width/height the backend can produce in a single call (RN/C-ABI carry width and height separately — for square SD models they're equal; for the IDL we fold them to the shared cap and document that asymmetric caps would need a future max_width_px / max_height_px split).
