/**
 * rExchange module — P2P crypto/fiat exchange within communities.
 *
 * Community members post buy/sell intents for CRDT tokens (cUSDC, $MYCO, fUSDC)
 * against fiat currencies. Solver matches intents, escrow handles settlement.
 *
 * All state stored in Automerge documents via SyncServer.
 * Doc layout:
 *   {space}:rexchange:intents    → ExchangeIntentsDoc
 *   {space}:rexchange:trades     → ExchangeTradesDoc
 *   {space}:rexchange:reputation → ExchangeReputationDoc
