Description

BatchDistributeHook enables push-based batch token distribution (up to 200 recipients per transaction) as a composable Uniswap V4 hook. It wraps [Spraay Protocol](https://spraay.app)'s on-chain batch functions (sprayToken, sprayETH, sprayEqual) so pool operators can distribute airdrops, holder rewards, and revenue shares alongside existing pool incentive mechanisms — without requiring recipients to claim.

The hook uses afterInitialize for pool registration and afterDonate to trigger batch distributions. It does not intercept swaps or liquidity operations.
