chore(deployments): record FeeOnTransferDetector on Robinhood, Arc, Avalanche, World Chain and Blast

[david-uniswap]

Records the 5 FeeOnTransferDetectors I deployed today in deployments/json. These were the only live chains without one. They're getting wired into Uniroute in Uniswap/backend#14301 (ROUTE-2128).

Chain	Address	v2 factory (constructor arg)
Robinhood (4663)	0xFdf682F51FE81Aa4898F0AE2163d8A55c127fbC7	0x8bcEaA40B9AcdfAedF85AdF4FF01F5Ad6517937f
Arc (5042)	0xB99894Da8066B106D66929Be879D3A05B4F595C4	0x89e5DB8B5aA49aA85AC63f691524311AEB649eba
Avalanche (43114)	0x693497d35E34F188b8dA1F5F952bE603e289Bf90	0x9e5A52f57b3038F1B8EeE45F28b3C1967e22799C
World Chain (480)	0x693497d35E34F188b8dA1F5F952bE603e289Bf90	0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f
Blast (81457)	0x693497d35E34F188b8dA1F5F952bE603e289Bf90	0x5C346464d33F90bABaf70dB6388507CC889C1070

• Deployed with forge create from this repo's util-contracts FeeOnTransferDetector at 047d585 (same initcode as the briefcase deployer). The three chains share an address because the deployer was at the same nonce on each.
• Entries match what forge-chronicles writes for this contract on recent chains (999, 4326, 59144, 4217): latest plus an appended history entry with initcodeHash (keccak of the deploy tx input, no 0x) and the _factoryV2 constructor input. Timestamps come from the deploy blocks.
• Arc's initcodeHash is identical to HyperEVM's Deploy-all record (1772a579…) because both use the same v2 factory address, so this build is byte-for-byte the same as the briefcase one.
• Verified on Etherscan + Sourcify for all 5, except Robinhood Etherscan, where their queue is stuck on "Pending" (Sourcify is a full match). World Chain is also on Blockscout.
• JSON only, no markdown. The chain .md files are already behind the JSON on main (SwapProxy / ReservesLens aren't in them), and regenerating them pulls in unrelated churn.
