How often cloud session events are batched can now be tuned remotely instead of being fixed.

What

The CCR client's stream-event batching interval moved from a fixed constant to an option read from a gate, so it can be tuned without a release.

Details
  • Read from tengu_ccr_stream_event_flush_ms, whose fallback is the old 100 ms constant.
  • Clamped to the range 0 to 60000 ms.
  • A non-finite value logs a warning and falls back to the default.
  • Plumbed through the remote-bridge transport setup and the reconnect paths.
