Patch Changes

• 15dce62: fix(alibaba): preserve unmapped usage fields in usage.raw

  Alibaba's usage was parsed with strict z.object schemas, so any field the
  provider does not explicitly map was dropped before reaching usage.raw —
  including prompt_tokens_details.cache_type, which names the caching mode and
  therefore the rate a cache read is billed at. Usage is now parsed loosely,
  nested objects included, matching what the anthropic provider does.

  A response carrying no usage now maps to a fully null usage object rather than
  one with noCache and cacheWrite zeroed and every other field undefined.

  This provider no longer depends on @ai-sdk/openai-compatible. It implements
  its own language model rather than building on the shared one, but still
  reached into that package's internals for usage conversion, tool preparation
  and finish-reason mapping. Those now live in the provider, alongside the
  equivalents in @ai-sdk/deepseek, @ai-sdk/groq, @ai-sdk/mistral and
  @ai-sdk/xai. Behavior is unchanged.
