Module session 

Sync session management for agent-to-agent state exchange.

Responsibility

Encapsulate the full shared CRDT state for a sync session, including vector clocks, counters, sets, registers, and maps. Provide a single merge entry point that delegates to each CRDT’s merge operation.

Guarantees

• All merges are commutative, associative, and idempotent.
• JSON round-trip is lossless.

Structs

AgentState
