Release notes:

Added time-based snapshot scheduling. Snapshots can now be triggered after a configurable wall-clock interval (snapshots.time_interval) elapses, in addition to the existing transaction-count threshold (snapshots.tx_count). A new snapshots.min_tx_count option (default 2) sets the minimum number of transactions required before a time-based snapshot fires. Snapshot timing state is replicated to backups via a new public:ccf.internal.snapshot_status internal table (#7731).
Added support for endpoints that defer their HTTP response until the submitted transaction reaches a terminal consensus state (committed or invalidated). Endpoint authors can call set_consensus_committed_function() when installing an endpoint to register a callback that is invoked once the transaction is globally committed or invalidated. The callback receives the ccf::TxID and a ccf::FinalTxStatus (either Committed or Invalid), and may inspect or modify the response before it is sent. A built-in ccf::endpoints::default_respond_on_commit_func is provided that returns the original response on commit, or an error on invalidation. See the logging sample app (/log/blocking/private) for example usage (#7562).
