style: fix linting errors and update README with new tools

- Auto-fix trailing spaces, curly braces, and indentation issues
- Clean up boolean comparisons and code formatting
- README automatically updated with new code injection tools:
  - browser_enable_debug_toolbar: Enable debug toolbar for client identification
  - browser_inject_custom_code: Inject custom JavaScript/CSS code
  - browser_list_injections: List all active code injections
  - browser_disable_debug_toolbar: Disable debug toolbar
  - browser_clear_injections: Remove custom code injections

All linting checks now pass successfully.
