Add PAM — Portable AI Memory interchange format specification

[danielgines]

What is PAM?

PAM (Portable AI Memory) is an open specification that defines a vendor-neutral JSON interchange format for AI user memories — similar to what vCard is for contacts or iCalendar for events.

It defines three composable JSON schemas:

• Memory Store — structured memories with types, confidence, temporal lifecycle, provenance, integrity verification
• Conversation — provider-agnostic conversation logs with DAG structure
• Embeddings — vector representations linked to memories

Why it belongs here: PAM is complementary to the tools in this list. Projects like Cognee, Mem0, and Letta could use PAM as an import/export format, enabling data portability between memory systems.
