[FEATURE] Option to disable "Yes, and don't ask again" in permission dialog

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently the permission dialog shows three options:
Do you want to proceed?
❯ 1. Yes

1. Yes, and don't ask again for similar commands in <path>
2. No

Use case: Users who want every command to always prompt for confirmation (security-conscious workflows) have no way to prevent option 2 from silently adding commands to the allow list. Gemini CLI supports disabling this "always allow" option natively.

Proposed Solution

Request: Add a setting (e.g. in settings.json) to hide or disable option 2, so users cannot accidentally permanently allow a command.
