Dispatch handler matches child issues that need coding (no PR yet,
assigned to a known agent) and SCPs ticket JSON to the agent's
queue directory via SSH. Includes dedup across queue/active/done
and posts dispatch comments on issues.
- Extend PipelineSignal with NeedsCoding, Assignee, IssueTitle, IssueBody
- Extend ForgejoSource to emit signals for unstarted children
- Add DispatchHandler with Match/Execute (SCP ticket delivery)
