[BUG] Cannot select or copy text from Dispatch window

Description

Text inside the Dispatch window cannot be selected or copied. No selection highlight appears on click-drag; clipboard remains empty after ⌘C. Works normally in the main Claude message area — only the Dispatch pane is affected.

Environment

• Claude Version: 1.2581.0 (f10398)
• Build timestamp: 2026-04-14T17:16:40.000Z
• OS: macOS
• Regression: Yes — copy/paste worked in the prior Claude Desktop build before this release

Reproduction

1. Open Claude Desktop → Dispatch tab
2. Spawn any Dispatch task (or open an existing one)
3. Attempt to select text in the Dispatch response area via click-drag
4. Attempt ⌘C after any selection

Expected: Text selects and copies to clipboard, same as the main chat area.
Actual: No selection highlight; clipboard unchanged.

Impact

Dispatch output is read-only AND uncopyable — any URL, command, SHA, or path Dispatch returns has to be re-typed by hand or forwarded via email workaround. Significant productivity regression for anyone relying on Dispatch for autonomous ops work.

Workaround attempted

None effective. Right-click context menu does not show Copy. Drag-select produces no highlight.
