Olaoluwa Osuntokun 0f61664ceb mempool+netsync: extend TxMempool interface for unified abstraction 
This commit extends the TxMempool interface to support both the legacy
TxPool and new TxMempoolV2 implementations transparently. The interface
now includes all methods required by the server, netsync, and mining
subsystems, enabling a feature flag to toggle between implementations
at runtime.

The extended interface adds critical methods that were previously only
available on the concrete TxPool type: RemoveOrphansByTag for peer
cleanup, MiningDescs for block template generation, and several internal
methods (RemoveDoubleSpends, RemoveOrphan, ProcessOrphans,
MaybeAcceptTransaction) used by netsync for transaction relay.

By abstracting these operations, we enable the server to use either
implementation without subsystem-specific code changes. The netsync
package now accepts the TxMempool interface rather than requiring the
concrete TxPool type, allowing transparent switching.

The MockTxMempool test implementation is updated to provide all new
interface methods, ensuring tests continue to work with the expanded
interface contract.

Overview

This package implements a concurrency safe block syncing protocol. The SyncManager communicates with connected peers to perform an initial block download, keep the chain and unconfirmed transaction pool in sync, and announce new blocks connected to the chain. Currently the sync manager selects a single sync peer that it downloads all blocks from until it is up to date with the longest chain the sync peer is aware of.
