aim_memory_add_facts

RETURNS: Array of {entityName, addedObservations} showing what was added (duplicates are ignored).
DATABASE: Adds to entities in the specified 'context' database, or master database if not specified.
EXAMPLES:
- aim_memory_add_facts({observations: [{entityName: "John", contents: ["Lives in Seattle", "Works in tech"]}]})
- aim_memory_add_facts({context: "work", observations: [{entityName: "Q4_Project", contents: ["Behind schedule", "Need more resources"]}]})
