Summary

Adds optional last_applied_assignment_id to worker heartbeat messages for NET-685.

This lets workers report the highest worker assignment they have fully applied, so the ping collector can persist that signal for later MVCC portal-promotion logic.

Notes

  • Field is optional for backward compatibility.
  • Uses proto field number 6; field 5 is already used by current_epoch.
  • Ordering semantics depend on NET-686.
  • Scheduler-side consumption is out of scope for this PR.

Validation

  • cargo test -p sqd-messages
