Module persist 

Persistent channel storage for MPP sessions.

Stores open payment channel state in a SQLite database at $TEMPO_HOME/channels.db (default: ~/.tempo/channels.db). This allows channel reuse across process invocations, avoiding the cost of opening a new on-chain channel for every cast / forge command.
