This release provides the **nop** mempool for applications that want to build
their own mempool. Using this mempool effectively disables all mempool
functionality in CometBFT, including transaction dissemination and the
`broadcast_tx_*` endpoints.

Also fixes a small bug in the mempool for an experimental feature, and reverts
the change from v0.37.3 that bumped the minimum Go version to v1.21.
