Qwen Code moves subagent sessions into a dedicated detail panel
This PR to QwenLM/qwen-code restructures how subagent runs are displayed in the web shell UI. Instead of dumping full child transcripts into the main conversation, the main thread keeps only a status card and summary, and selecting a task opens a dedicated detail view backed by a full transcript load plus an independent SSE stream.
Highlights:
- Wide layouts use a side panel; narrow or split layouts use a drawer.
- Parallel agent entries all route through the same detail path.
- Active subagents can be cancelled independently.
- The backend exposes workspace-scoped resolution/cancellation routes and virtualizes persisted transcripts as sessions.
- Main-turn metrics now combine main-agent usage with root subagent execution summaries without retaining the child content in the parent transcript.
The motivation is to keep long agent traces from overwhelming the main chat while preserving full inspection and reconnect behavior on demand.
