## Title

    Proposed fix: [Gemini CLI Windows sandbox] 'Sandbox request rejected: Allowed path does not exist ... On Windows, granular sandbox access can only be granted to existing paths'

## Body

    Recommended action: Create the directory beforehand, or grant an existing parent that is acceptable to open, then retry.
    
    Option: Create the directory beforehand, or grant an existing parent that is acceptable to open, then retry. [evidence: official_recommended_action]
    Applies when: Granting extra sandbox read/write paths (policy allowedPaths / additional write paths) on Windows
    Steps:
    1. mkdir the target path before the sandboxed command.
    2. Or add an existing parent directory to the allowed write paths.
    Expected: The error no longer appears.
