 * @title CurvePoolRegistry\r
 * @author UniversalRouterTeam\r
 * @notice Centralized, owner-controlled registry for whitelisting safe and verified Curve pools.\r
 * @dev\r
 * This contract is designed to work with aggregator modules (like CurveDexModule) that prioritize\r
 * whitelisted pools over general pools discovered via the Curve MetaRegistry.\r
 *\r
 * - Pools are stored by a canonical key: keccak256(sorted(tokenA, tokenB)).\r
 * - All pool management functions (`setVerifiedPools`, `clearVerifiedPools`) are restricted to the contract owner.\r
 * - Provides a single source of truth for secure and reliable Curve pool addresses.\r
 *\r
 * Key Components:\r
 * - `verifiedPools`: Mapping of canonical pair keys to approved pool addresses.\r
 * - `getVerifiedPools`: Public view function conforming to IPoolRegistry for module consumption.\r
 * - `_pairKey`: Internal helper to ensure order-independent storage and retrieval.\r
 *\r
 * Designed to enhance security and reliability of decentralized exchange routing.\r
