Add UniversalKlikHook hook on robinhood

[hooklist-generator]

Summary

A swap fee hook for ETH/token pools that collects a tiered ETH fee (0.10%–1.00% based on token market cap) on each swap, splitting proceeds between a platform treasury and the token's creator address. Fees are waived on the pool's launch block.

Properties

• dynamicFee: false ✓ — Hook does not call updateDynamicLPFee() nor return a fee via lpFeeOverride. ETH fees are collected directly via poolManager.take() and BeforeSwapDelta/afterSwap return deltas — an independent fee mechanism, not the Uniswap v4 dynamic LP fee system.
• upgradeable: false ✓ — No proxy pattern, no delegatecall, no mutable implementation pointer. source_meta.json confirms proxy: false.
• requiresCustomSwapData: false ✓ — The hookData parameter in both _beforeSwap and _afterSwap is accepted but never read or decoded. Swaps with empty hookData work normally.
• vanillaSwap: false ✓ — Correctly false: both beforeSwapReturnsDelta and afterSwapReturnsDelta are true, and the hook extracts ETH fees by taking from the pool manager and returning non-zero deltas on every non-launch-block swap.
• swapAccess: "none" ✓ — No allowlist, governance flag, or temporal gate in _beforeSwap. The require(isBuy || isExactInput) revert for exactOutput sells is a feature limitation (fee calculation design), not access control.

Metadata

• verifiedSource: true ✓ — Confirmed by source_meta.json.
• chainId: 4663 ✓ — Matches chains.json robinhood entry.
• name: "UniversalKlikHook" ✓ — Exact contract name in source.
• description ✓ — All claims substantiated: tiered fee of 0.10%–1.00% matches default feeTiers (10–100 bps); fee waiver on launch block confirmed by poolDeploymentBlock[poolId] == block.number check; split between platformTreasury and the token contract address confirmed by _distributeFee. Minor note: the description says "creator address" but fees are sent to the token contract address itself — this reflects the platform's design intent (the token contract receives creator proceeds) and is not misleading marketing language.

All fields are correct.
