server : add thinking content blocks to Anthropic Messages API (#18551) * server : add thinking content blocks to Anthropic Messages API Add support for returning reasoning/thinking content in Anthropic API responses when using models with --reasoning-format deepseek and the thinking parameter enabled. - Non-streaming: adds thinking block before text in content array - Streaming: emits thinking_delta events with correct block indices - Partial streaming: tracks reasoning state across chunks via anthropic_has_reasoning member variable Tested with bartowski/DeepSeek-R1-Distill-Qwen-7B-GGUF model. * server : fix Anthropic API streaming for thinking content blocks Add signature field and fix duplicate content_block_start events in Anthropic Messages API streaming responses for reasoning models. * server: refactor Anthropic streaming state to avoid raw pointer Replace raw pointer to task_result_state with direct field copies: - Copy state fields in update() before processing chunk - Use local copies in to_json_anthropic() instead of dereferencing - Pre-compute state updates for next chunk in update() This makes the data flow clearer and avoids unsafe pointer patterns.
