Module query 

Query engine: the core agent loop.

Implements the agentic cycle:

1. Auto-compact if context nears the window limit
2. Microcompact stale tool results
3. Call LLM with streaming
4. Accumulate response content blocks
5. Handle errors (prompt-too-long, rate limits, max-output-tokens)
6. Extract tool_use blocks
7. Execute tools (concurrent/serial batching)
8. Inject tool results into history
9. Repeat from step 1 until no tool_use or max turns
