feat: add Aegis protocol entry

[dak-agent]

Aegis

Adds mainnet/aegis.jsonc. Aegis (aegis.markets) is programmable infrastructure for Uniswap v4 pools — a dynamic (volatility-aware) fee hook (DFM) plus a pool-native liquidity and credit engine. It attaches to Uniswap v4 pools rather than replacing them.

Why

Aegis hooks are integrated for Monad in kyberswap-dex-lib (the hook constant.go explicitly tags the Monad deployments):

• Aegis hook v1.0 on Monad: KyberNetwork/kyberswap-dex-lib#1449
• Aegis hook v1.1 on Monad: KyberNetwork/kyberswap-dex-lib#1488

Addresses

Hook addresses are taken from kyberswap-dex-lib's Aegis config (uniswap/v4/hooks/aegis/constant.go, entries commented // monad 1.0 / // monad 1.1):

• Hook_v1.0: 0xb4f4949e8D0a177bb6D2fea33e9516Bb219610cc
• Hook_v1.1: 0xe449E013004DB4a5681E9622ca10c5Ba0eA610cc

Notes

• Aegis is a Uniswap v4 hook layer rather than a standalone AMM, so reviewers may prefer to keep it as its own entry (as done here) or fold it into the Uniswap entry — flagging for a maintainer call.
• Stubbed by Monad Foundation from third-party (KyberSwap) integration data. The Aegis team should verify and expand the address set (DFM / policy-manager / engine contracts) as needed.
• Validated locally: passes required-field, category, address-format, duplicate-address, and canonical-contract checks.
