Module tool_extractor 

Streaming tool call extractor for instruction-tuned models.

When a model emits <tool_call>...</tool_call> blocks in its text output (because tools were injected via XML into the system prompt), this module provides a streaming state machine that detects those blocks and converts them into proper NormalizedEvent tool call events.
