Add RareFriendsHook (mainnet) to routing allowlist

[spokesz]

Summary

Adds the Rare Friends hook on Robinhood Chain (4663) so its RF/WETH v4 pool can route through the Uniswap interface.

The hook collects a fixed 500-bps WETH-side fee on buys and sells, funding rewards for activated Rare Friends NFTs.

Addresses

• Hook: 0x7A65d0194e6Cc43971C31CE7D1471Da01D42A0cC
• RF token: 0x0779369854d3EcdEA927206718FFD7730C67B71f

Routing details

Trading is not restricted to this hooked pool. RF can trade in other pools, and swaps through this pool do not require a particular router or
custom hook data.

Both return-delta flags are used because fees are always collected in WETH:

Exact-input RF buy / exact-output RF sell =

• beforeSwap: WETH is specified

Exact-input RF sell / exact-output RF buy

• afterSwap: WETH is unspecified; use the actual WETH delta

Only one fee path runs per swap. Specified-WETH fees use the requested amount; our Market rejects partial fills.

Safety notes

• Non-upgradeable hook with a constant fee rate. The owner can change the rewards destination.
• Permissions: beforeInitialize, beforeSwap, afterSwap, and both swap-return-delta flags.
• Bound to one RF/WETH pool and its PoolManager.
• Reward funding occurs synchronously; a funding failure reverts the swap.
• RF has no additional minting, transfer tax, blacklist, or pause. Balance changes synchronize temporary Friends through the immutable Generations
  contract.
