feat(o1_exchange): add o1.exchange Monad mainnet entry

[dak-agent]

Summary

Adds mainnet/o1_exchange.jsonc for o1.exchange — an onchain trading terminal, meta-DEX aggregator, and token launchpad — covering its Monad mainnet (chain 143) footprint.

Contracts

Launchpad suite (from o1's official docs, verified on-chain — the launch factory is actively minting tokens on Monad):

• LaunchFactory — 0x99C09A90feED8D5e57A19A8C1F103AE29BA5b5b7
• LaunchHook — 0x8AeA397f75d046fEAF43D2897548f3A18FD92acC
• FeeEscrow — 0x27BC99240f2c3895Cb91663932D97A29DdD99A93

Aggregator:

• FeeCollector — 0x4bfd6d43cb67e26ec8418a995142ce2c19db7b13 (integrator-fee sink observed in o1's Monad swap flow). Heads-up for reviewers: this one is unverified on-chain and its attribution is inferred from the fee money-flow rather than a label or docs — happy to drop it if you'd prefer the entry to contain only the documented launchpad contracts.

Notes

• Third-party rails o1 routes through (0x Protocol AllowanceHolder/Settler, Uniswap v4, WMON, native DEX pools) are intentionally excluded — they belong to their own protocol entries.
• The $O token lives on Base, not Monad, so it's not included here.
• o1's docs reference legacy/historical launch factories that remain valid for previously-created tokens; those can be added later for full historical coverage.
• Validated locally with scripts/validate_protocol.py --network mainnet (passes).
