feat: expose rpc listener

CHANGELOG.md

@@ -9,7 +9,7 @@
 - Validator now persists validated transactions ([#1614](https://github.com/0xMiden/miden-node/pull/1614)).
 - [BREAKING] Remove `SynState` and introduce `SyncChainMmr` ([#1591](https://github.com/0xMiden/miden-node/issues/1591)).
 - Introduce `SyncChainMmr` RPC endpoint to sync chain MMR deltas within specified block ranges ([#1591](https://github.com/0xMiden/miden-node/issues/1591)).
-- Fixed `TransactionHeader` serialization for row insertion on database & fixed transaction cursor on retrievals ([#1701](https://github.com/0xMiden/miden-node/issues/1701)).
+- Re-Introduce `RpcListener` & expose remote prover as a library to allow instantiation on other crates ([#1709](https://github.com/0xMiden/miden-node/issues/1709)).
 
 ### Changes

 - Improved tracing span fields ([#1650](https://github.com/0xMiden/miden-node/pull/1650))
  - Replaced NTX Builder's in-memory state management with SQLite-backed persistence; account states, notes, and transaction effects are now stored in the database and inflight state is purged on startup ([#1662](https://github.com/0xMiden/miden-node/pull/1662)).
 - [BREAKING] Reworked `miden-remote-prover`, removing the `worker`/`proxy` distinction and simplifying to a `worker` with a request queue ([#1688](https://github.com/0xMiden/miden-node/pull/1688)).
+- Fixed `TransactionHeader` serialization for row insertion on database & fixed transaction cursor on retrievals ([#1701](https://github.com/0xMiden/miden-node/issues/1701)).
