ML Kit has no synchronous status check, so isAvailable() answered from a cached status or a guess, and it counted a downloading model as available where apple and ADK don't. getModelInfo() reports the exact state. Builds on #367. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Removes isAvailable() from the provider, the transcription model and the AppleTranscription module, matching the Android provider. getModelInfo() reports availability and why the model is unavailable. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
Stacked on #367.
isAvailable()isn't an AI SDK API, and providers disagree on what it means mid-download: apple's language model saysfalse, ADK saysfalsewhile downloading buttruewhen downloadable, and Android saidtruefor both. ML Kit also has no synchronous status check, so Android's version answered from a cached status or from whether AICore is installed, which reports true on a Pixel 9 Pro where the Nano 4 preview and en-US speech recognition are unavailable.I removed
isAvailable()from the Android and Apple providers, their language and transcription models, andAppleTranscription, along with Android's status cache and AICore package query.getModelInfo()reports the exact state, which an app needs anyway to show a download or explain why the model is unavailable. Apple's transcription info keeps itsisAvailablefield. ADK is left alone since #368 removes it.The example app now checks availability asynchronously through
getModelInfo().Breaking changes
apple.isAvailable(),apple.transcriptionModel().isAvailable()andAppleTranscription.isAvailable()are gone; usegetModelInfo(), which rejects withUNSUPPORTED_OSbefore iOS 26.Test plan
