Module contracts 

Contracts bridge — implements agentic-contracts v0.2.0 traits for Memory.

This module provides MemorySister, a contracts-compliant wrapper around the core MemoryGraph + engines. It implements:

• Sister — lifecycle management
• SessionManagement — append-only sequential sessions
• Grounding — BM25-based claim verification
• Queryable — unified query interface
• FileFormatReader/FileFormatWriter — .amem file I/O

The MCP server can use MemorySister instead of raw graph + engines to get compile-time contracts compliance.
