Always Allow for Bash permissions does not persist in Cowork mode code tasks

Bug Description

When using Cowork mode (Dispatch), each new code task spawned via start_code_task asks for Bash permission again, despite clicking Always Allow multiple times in previous sessions.

Steps to Reproduce

1. Open Cowork/Dispatch mode
2. Start a code task that requires Bash
3. When prompted Allow Claude to use Bash?, click Always Allow
4. Wait for another step that needs to run Bash
5. The Allow Claude to use Bash? dialog appears again

Expected Behavior

After clicking Always Allow, Bash permissions should persist in cowork forever?

Actual Behavior

Always Allow has no effect. Every new code task session asks for permission again. User reports clicking it 5+ times with no change.

Environment

• Claude Desktop app with Cowork mode (research preview)
• macOS
• April 2026

Impact

This significantly degrades the Cowork experience for developers who are using cowork mode. Each permission dialog interrupts workflow and wastes time unnecessarily
