/**
 * Validates config/deployment-status.json for "minimum viable deployed graph".
 * Use in CI so deployment-realistic sim cannot run with half-filled state.
 *
 * Rules:
 * - If bridgeAvailable === true on a chain, cwTokens must include at least cWUSDT and cWUSDC (phase 1).
 * - For each pmmPool: role in {defense, public_routing}, feeBps and k present,
 *   base/quote (or tokenIn/tokenOut) exist in cwTokens or anchorAddresses.
 *
 * Exit code: 0 if valid, 1 if invalid (and prints errors to stderr).
