mateo-berri 32bf1aba29 fix(anthropic): stop signing replayed thinking blocks and strip reasoning_content
A reasoning item id is not an Anthropic signature. Passing it off as one got the
block replayed to Anthropic and Bedrock as if it were real, and every backend that
verifies signatures rejected the turn. Thinking blocks now come back unsigned, and
the streaming path no longer emits a signature_delta for them.

Azure AI Foundry, Fireworks, and vLLM reject unknown message fields, so they now
strip reasoning_content alongside thinking_blocks the way Mistral already did.

The thinking-block helpers take ChatCompletionThinkingBlock and
ChatCompletionRedactedThinkingBlock instead of loose mappings.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.
