stonfi_distributed_sync-v0.1.0

• Restore optional per-handler worker processing-stat summaries in application
  logs. The default zero period disables them; configure a non-zero period with
  Worker::builder(...).with_stats_logging_period(...).
• Label the processing-stat log table's handler column as handler_id.
• Change DistributedHandler::into_sync and
  Worker::builder(...).add_handler to consume owned handlers instead of
  Arc<Handler>. Applications should construct independent handler instances
  for coordinator and worker processes.
• Return the private sync adapter from DistributedHandler::into_sync so it can
  be registered directly; convert it explicitly to a core Synchronizer only
  when its progress is an upstream dependency.
• Make DistributedHandler::into_sync infallible, share one absolute deadline
  across distributed task attempts, and pass polling, reconnect, and lifecycle
  durations through standard Tokio semantics. Millisecond wire values saturate
  to u64::MAX only on numeric overflow.
• Publish the package on crates.io after stonfi_sync_core and use registry
  releases for workspace dependencies.
