Add ClaudeAnthropicPlugin for direct access to Anthropic's API at api.anthropic.com, bypassing the need for Google Vertex AI. Key differences from CLAUDE-4-VERTEX: - Uses x-api-key header authentication - Model specified in request body - anthropic-version header instead of body parameter - Stream parameter in request body Added models: - claude-sonnet-4: Claude Sonnet 4 via direct API - claude-45-sonnet: Claude 4.5 Sonnet via direct API - claude-45-opus: Claude 4.5 Opus via direct API All models support streaming, tool calling, vision, and document (PDF) input via the inherited Claude4VertexPlugin functionality. Includes unit tests and integration tests.
