Add LauncherHook hook on ethereum

[hooklist-generator]

Summary

A token launchpad hook that enables creators to initialize ETH/token pools and seed one-sided liquidity from a configurable percentage of the token's total supply. Creators can later withdraw their full position (principal and accrued fees) via creator-gated entry points.

Flags

Address 0x...50500 — lowest 14 bits = 0x0500 = 0b0000_0101_0000_0000:

Bit	Flag	Address	JSON
10	afterAddLiquidity	1	true ✓
8	afterRemoveLiquidity	1	true ✓
all others	—	0	false ✓

Confirmed by the constructor's Hooks.validateHookPermissions call, which hard-codes identical permissions and reverts if the deployed address bits do not match.

Properties

• dynamicFee: false ✓ — No beforeSwap hook; no updateDynamicLPFee call anywhere in the contract.
• upgradeable: false ✓ — poolManager is immutable; no proxy pattern, no delegatecall to a mutable address, no SELFDESTRUCT. source_meta.json confirms proxy: false.
• requiresCustomSwapData: false ✓ — No swap hooks; hookData is never inspected during swaps.
• vanillaSwap: true ✓ — No swap flags at all; satisfies the "must be true if the hook has no swap flags" rule.
• swapAccess: "none" ✓ — No beforeSwap / afterSwap callbacks.

Metadata

• name: LauncherHook matches the Etherscan-verified contract name.
• chainId: 1 (Ethereum mainnet) is correct.
• verifiedSource: true, confirmed by source_meta.json.
• description: Accurate. The contract seeds one-sided token liquidity sized as pctBps basis points of totalSupply() (addLiquidity), holds the LP internally, and allows the creator to withdraw principal plus accrued fees in both currencies via removeLiquidity (creator-gated). No promotional, audit, or safety language present.

All checks pass.
