Entity Memory: Facts and Events (Deep Dive)

"""
Entity Memory: Facts and Events (Deep Dive)
============================================
Semantic (facts) vs episodic (events) memory for entities.

Entity Memory stores knowledge about external entities:
- Facts: Timeless truths ("Acme uses PostgreSQL")
- Events: Time-bound occurrences ("Acme raised $30M on Jan 15")

AGENTIC mode gives the agent tools to create/update entities.

Compare with: 04_always_extraction.py for automatic extraction.
See also: 01_basics/5a_entity_memory_always.py for the basics.
