Add AegisHook hook on monad

[hooklist-generator]

Summary

A Uniswap v4 hook that applies dynamic fees to swaps via an external DynamicFeeManager, integrates oracle price observations after each swap, and periodically reinvests accumulated hook fees into full-range LP positions via an AegisEngine.

Warnings

• Submitter-proposed name "Aegis cEngine" rejected: does not match contract name AegisHook; the label "cEngine" is not present in the verified source. Using "AegisHook".
• Submitter-proposed description rejected: describes the broader AEGIS system rather than the hook's actual on-chain mechanics. Using AI-generated description.

Closes #661

Confirmed also by getHookPermissions() in the verified source.

Properties

• dynamicFee: true ✓ — _beforeSwap calls DYNAMIC_FEE_MANAGER.prepareSwap() to get activeFee and returns activeFee | LPFeeLibrary.OVERRIDE_FEE_FLAG, overriding the LP fee dynamically on every swap.
• upgradeable: false ✓ — source_meta.json confirms proxy: false. All external dependencies (ORACLE_MANAGER, DYNAMIC_FEE_MANAGER, AEGIS_ENGINE, LIMIT_ORDER_MANAGER) are immutable. No delegatecall, mutable implementation slot, or SELFDESTRUCT.
• requiresCustomSwapData: false ✓ — The hookData parameter in _beforeSwap is unnamed and completely unused. Swaps function correctly with empty hookData.
• vanillaSwap: false ✓ — Correctly false: dynamicFee is true, and both beforeSwapReturnsDelta and afterSwapReturnsDelta are active (used to charge a hook fee cut from swap input).
• swapAccess: "none" ✓ — _beforeSwap applies no gating or revert-based access control on swaps. The Pausable modifier only gates _tryReinvest (fee reinvestment), not swap execution itself.

Metadata

• chainId: 143 ✓ — Matches monad in chains.json.
• name: "AegisHook" ✓ — Matches the contract name exactly. No promotional or endorsement language.
• verifiedSource: true ✓ — Confirmed by source_meta.json ("verified": true).
• description ✓ — All three claims (dynamic fees via DynamicFeeManager, oracle observations after swaps, fee reinvestment into full-range LP via AegisEngine) are substantiated by the source logic in _beforeSwap, _afterSwap, and _tryReinvest respectively. No marketing or audit language.
