Unused contract variable
Unused contract variables
Description
Several variable inside TokenLaunchHook.sol is never used. Remove it will make protocol more gas efficient.

Risk
Very minimal risk on contract
Likelihood:
It will always occurs whenever protocol is using current code
Impact:
Less gas efficient
Proof of Concept
Run test suite with forge test. Note down on the gas fee for each function
Remove all error and used variable
Run test suite with forge test to ensure everything is fine & gas fee for each function
Recommended Mitigation
Remove all unused error and state variables
