Vulnerability details

Impact

'immutable' greatly reduces gas costs. There are variables that do not change so they can be marked as immutable to greatly improve the gast costs. Examples of such variables are all variables in TreasuryVester except lastUpdate.

Agree with the finding, immutable will save gas as no storage slot is allocated to those variables
