The execution of MetadataRenderer.addProperties should be careful enough to not break the invariant numStoredProperties + numNewProperties < 16. Because there is no way to remove properties and when properties.length >= 16, there is revert at https://github.com/code-423n4/2022-09-nouns-builder/blob/7e9fddbbacdd7d7812e912a369cfd862ee67dc03/src/token/metadata/MetadataRenderer.sol#L194 when i >= 15. This could lead to revert on onMinted and the Auction will be in DOS status. Consider have a function to remove properties or have a check when adding new properties

msg.value
here is unclear and also does not have any checks. As far as I know, the Treasury.execute
uses Treasury fund, so make Governor.execute
payable
is no need
