Inconsistency in agent session management between CLI and desktop app

The claude agents CLI command suggests there are UI equivalents for managing background agents (the error message directs users to use --json for machine-readable output), but the Claude Code desktop app lacks an "Agents" panel or UI for viewing/attaching to running agents.

Steps to reproduce

1. Start a background agent
2. Open the Claude Code desktop app
3. Look for an Agents panel or way to view running agents
4. Compare with the CLI experience via claude agents --json

Expected behavior

The desktop app should have a consistent way to view and attach to background agents, or the CLI error message should clarify that this feature is only available via CLI.

Current behavior

• Desktop app: no visible Agents panel or session management UI
• CLI: claude agents error suggests interactive UI options exist
• Web (claude.com/code): unclear if similar UI exists there

Environment

• Claude Code desktop app
• macOS
