feat: Add auto-accept indicator and toggle

- This commit introduces a visual indicator in the CLI to show when auto-accept for tool confirmations is enabled. Users can now also toggle this setting on/off using Shift + Tab.
- This addresses user feedback for better visibility and control over the auto-accept feature, improving the overall user experience.
- This behavior is similar to Claude Code, providing a familiar experience for users transitioning from that environment.
- Added tests for the new auto indicator hook.
