- Relax ClaimAgentTask SQL constraint from per-issue to per-(issue, agent)
serialization, allowing different agents to run in parallel on the same issue
- Update GetActiveTaskForIssue API to return all active tasks (array) instead of
just the first one
- Refactor AgentLiveCard to render one card per active task, routing WebSocket
messages by task_id for independent timelines
- Fix shouldEnqueueOnComment to use per-agent dedup so a mentioned agent's
pending task doesn't block the assigned agent's on_comment trigger
Closes MUL-160
