Add LimitOrderHook hook on base

[hooklist-generator]

Summary

A Uniswap v4 Hook that enables on-chain limit orders on supported liquidity pools.

Users can set a target price, and when the pool price reaches the specified price, the Hook automatically executes the order. This enables users to place limit orders directly on Uniswap v4.

Properties

• dynamicFee: false ✓ — No beforeSwap, no updateDynamicLPFee() call anywhere in the contract.
• upgradeable: false ✓ — treasury is immutable; no proxy pattern, no delegatecall to mutable targets, no SELFDESTRUCT.
• requiresCustomSwapData: false ✓ — hookData parameter in _afterSwap is unused; swaps execute correctly with empty hookData.
• vanillaSwap: false ✓ — _afterSwap calls poolManager.modifyLiquidity() and poolManager.mint() to fill crossed limit orders, performing non-trivial pool state changes inside the afterSwap callback.
• swapAccess: "none" ✓ — beforeSwap flag is not set, so there is no access control on swaps.

Metadata

• name: "LimitOrderHook" ✓ — Exact contract name from verified source.
• chainId: 8453 ✓ — Matches base in chains.json.
• verifiedSource: true ✓ — Confirmed by source_meta.json.
• description ✓ — Accurately describes the one-tick out-of-range liquidity limit order mechanism. No audit, safety, or marketing language.
