Extraction Limits: Preventing Runaway Loops
============================================
Configure max_updates_per_run to cap memory updates per extraction.

When learning stores extract information, they call tools (add_memory,
update_profile, etc.) in a loop. Without limits, a model that keeps
requesting tools can loop indefinitely.

max_updates_per_run caps tool executions:
- LearningMachine level: applies to all stores (default: 10)
- Store config level: overrides the global for that store
