Belong CheckIn & DEX Integration

The economic core of the Belong platform: venue deposits, customer payments, promoter attribution, ERC-1155 credit accounting, staking-tier fees, and $LONG buyback/burn routing, all in one settlement flow. Paired with DEX swap infrastructure for $LONG across Uniswap/Pancake-style routers (V3/V4): Permit2 approval handling, price-feed-based slippage checks, fork-tested before deploy.
