Walkthrough

This update removes the entire xfeemarket module and all its code, configuration, simulation, tests, and protobuf definitions. It refactors fee market logic to rely on the EVM module and moves fee burning to the tax module's end blocker. Application and ante handler logic are updated to integrate Cosmos EVM modules and eliminate xfeemarket dependencies.

Poem

The fee market's gone, its code set free,
Burned away in tax, as clean as can be.
Ante flows anew, with EVM in tow,
Genesis reborn, old modules let go.
With rabbits a-hop and contracts to run,
The chain leaps ahead—onward, omstead, to fun!
