QUEUE + manual approval causes unintended auto-rejections & Enter key UX issue

[boukeversteegh]

Description

When using the new QUEUE feature with manual approval enabled, a follow-up message placed in the queue causes the next approval gate to be auto-handled. The run immediately continues and the LLM behaves as if the pending request was rejected, without user confirmation.
This does not happen when auto-approve is enabled.

Steps to Reproduce

1. Disable auto-approve.
2. Give the agent a task that will eventually require approval.
3. Queue a message, e.g., "and after that please build xyz".
4. Wait until the agent reaches a step that requires approval.
5. Observe: it immediately continues, and the LLM output indicates the request was treated as rejected.

Expected Behavior

• When manual approval is enabled, reaching an approval step should pause and wait for explicit user action, regardless of queued messages.
• In general, sending a free-form text message and pressing Enter should not implicitly reject the request.
  Instead, the UI should guide the user to explicitly approve or reject.
  This allows for workflows like “Yes, and …” where the user can append follow-up instructions without wasting tokens on re-summarization or prematurely triggering a task_complete action.

Actual Behavior

• The run continues automatically and the model assumes the approval request was rejected.
• In non-QUEUE scenarios, pressing Enter with a text reply still counts as a rejection.

Impact

• Breaks manual-approval workflows; QUEUE + manual approval are effectively incompatible.
• Discourages quick inline approval with appended instructions.

Environment

• Roo Code version: 3.25.11
• Platform: Windows
• Manual approval: Enabled
• Auto-approve: Disabled
• QUEUE: Enabled

Possible Workaround

Enable auto-approve (issue does not reproduce).

I'm here to help out the maintainers and am going to see if I can fix this issue! I'll investigate the QUEUE feature interaction with manual approval and work on preventing the unintended auto-rejections. 🔧

PR #6997 has been created to fix this issue.

The fix prevents the queue from interfering with the manual approval workflow by:

1. Ensuring queue processing pauses when approval buttons are showing (added enableButtons check to the queue processing effect)
2. Making sure messages typed during approval are properly queued instead of being sent immediately (added enableButtons condition to the queueing logic)

The changes are minimal and focused on the specific interaction between the queue and approval features, maintaining backward compatibility with existing functionality.
