2.3.0

This release makes the hydra-node noticeably faster: snapshot processing no longer re-evaluates Plutus scripts for transactions it already validated on receipt, cutting redundant script execution from the hot path and significantly increasing sustained in-head throughput — especially for script-heavy workloads.

It also adds native support for HD-wallet (PaymentExtendedKey) signing keys and node configuration via a YAML file.

A batch of resilience fixes rounds it out: event-log rotation no longer drops pending deposits, deposit observations are scoped to the current head, the Blockfrost backend got error handling and datum-decoding fixes, and a network-layer PersistentQueue deadlock was resolved.
