VSCode: Selection menus interrupt "Queue next message" input, causing inadvertent confirmations

Problem

The VSCode extension displays "Queue next message" placeholder during Claude processing, encouraging users to type ahead. However, selection menus can appear mid-sentence while users are typing, interrupting input and causing inadvertent option selections.

Impact

• Selection menus interrupt typing mid-word/mid-sentence
• Users accidentally confirm actions with serious consequences, such as:
• Exiting Plan Mode → entering Automatic Edit Mode
• Approving tool execution without review
• Granting access to OS-level commands

Reproduction

1. Start task in Plan Mode
2. While Claude is processing, begin typing queued message (as UI encourages)
3. Selection menu appears mid-sentence (e.g., "Exit Plan Mode?")
4. Continued typing inadvertently selects option (Enter key confirms default)
5. Mode change or action executes without explicit user intent

Expected Behavior

Selection menus should not interrupt active input in the "Queue next message" field.

Suggested Fix

Defer selection prompts until user submits their queued message, or require explicit selection method (mouse click / arrow keys + Enter) that can't be triggered by typing.

Scope

VSCode extension specific
