Module executor 

Tool executor: manages concurrent and serial tool execution.

The executor partitions tool calls into batches:

• Read-only (concurrency-safe) tools run in parallel
• Mutation tools run serially

This mirrors the streaming tool executor pattern where tools begin execution as soon as their input is fully parsed from the stream, maximizing throughput.
