Module IFeeManager 

FeeManager interface for managing gas fee collection and distribution.

IMPORTANT: FeeManager inherits from TIPFeeAMM and shares the same storage layout. This means:

• FeeManager has all the functionality of TIPFeeAMM (pool management, swaps, liquidity operations)
• Both contracts use the same storage slots for AMM data (pools, reserves, liquidity balances)
• FeeManager extends TIPFeeAMM with additional storage slots (4-15) for fee-specific data
• When deployed, FeeManager IS a TIPFeeAMM with additional fee management capabilities

Storage layout:

• Slots 0-3: TIPFeeAMM storage (pools, pool exists, liquidity data)
• Slots 4+: FeeManager-specific storage (validator tokens, user tokens, collected fees, etc.)

interface IFeeManager {
    struct FeeInfo { uint128 amount; bool hasBeenSet; }
    function userTokens(address user) external view returns (address);
    function validatorTokens(address validator) external view returns (address);
    function setUserToken(address token) external;
    function setValidatorToken(address token) external;
    function distributeFees(address validator, address token) external;
    function collectedFees(address validator, address token) external view returns (uint256);
    event UserTokenSet(address indexed user, address indexed token);
    event ValidatorTokenSet(address indexed validator, address indexed token);
    event FeesDistributed(address indexed validator, address indexed token, uint256 amount);
    error OnlyValidator();
    error OnlySystemContract();
    error InvalidToken();
    error PoolDoesNotExist();
    error InsufficientFeeTokenBalance();
    error InternalError();
    error CannotChangeWithinBlock();
    error CannotChangeWithPendingFees();
    error TokenPolicyForbids();
}
