[codex] Add WWDC26 Apple Intelligence APIs

[grabbou]

Summary

Adds the WWDC26 Apple Intelligence API surface to @react-native-ai/apple, with the common paths exposed through AI SDK-compatible models and Apple-only behavior kept behind providerOptions.apple or low-level native helpers.

What changed

• Added Apple provider types and exports for model IDs, provider options, model info, image styles, image personalization, and context controls.
• Added apple.getModelInfo({ locale, model }) and native getModelInfo(locale, model) for availability, locale support, supported languages, context metadata, and capability flags.
• Added model selection for SystemLanguageModel.default and iOS 27 PrivateCloudComputeLanguageModel through providerOptions.apple.model and createAppleProvider({ model }).
• Added context helpers inspired by Apple Dynamic Profile/history utilities: rolling message windows and completed tool-call pruning.
• Added AI SDK image prompt support by converting image/* file parts into Apple Foundation Models prompt attachments.
• Added Image Playground generation through apple.imageModel(), including style options, source image serialization, and personalization when the SDK exposes ImagePlaygroundOptions.
• Added iOS 27 Vision built-in tool support for OCRTool and BarcodeReaderTool via providerOptions.apple.builtInTools.
• Extended the low-level native API with generateImages and getModelInfo wrappers.
• Revamped Apple generation docs and package README to cover requirements, SDK gates, PCC, image prompts, image generation, Vision tools, context strategy, and direct native API boundaries.

Notes

Several Apple Intelligence symbols are SDK-gated as well as OS-gated. The implementation compile-gates newer APIs so current Xcode 26.0 / iPhoneOS 26.0 SDK builds keep working while newer SDKs can enable the newer paths.

Full iOS 27 native compilation still needs validation on an SDK that exposes the iOS 27 Foundation Models symbols.

Validation

• bun run --filter='@react-native-ai/apple' typecheck
• bun run --filter='@react-native-ai/apple' prepare
• git diff --check
• Targeted swiftc -typecheck probes for local SDK-visible Foundation Models and Image Playground APIs
