 * \r
 * Features:\r
 * - Two-phase system: Bonding curve (80%) → Automated liquidity (20%)\r
 * - Constant product formula (x*y=k) for fair, deterministic pricing\r
 * - Configurable fees with platform/creator revenue split\r
 * - Creator sell lock protection (1 hour after pre-buy)\r
 * - Automatic Uniswap V2 liquidity provision with LP burn\r
 * - Pull payment pattern for graceful failure handling\r
 * - **OWNERSHIP AUTO-RENOUNCED AFTER BONDING COMPLETES** (100% decentralized)\r
