fix: Ensure user written ! is treated opaquely if not in shell mode\n\n- Addresses an issue where commands prefixed with ! (e.g., !ls) were incorrectly handled by the shell command processor if the ! was added after initially typing the command.\n- Ensures that such commands are correctly forwarded to the Gemini model.\n- Updates useGeminiStream to be aware of shell mode to properly manage streaming state.\n\nFixes https://buganizer.corp.google.com/issues/418761305
