Add command line options to ExampleRunner and improve demo keystrokes

- Added --fake-driver/-f option to force FakeDriver via ConfigurationManager
- Added --timeout/-t option to configure timeout in milliseconds
- ExampleRunner no longer injects additional keys (relies on example mode)
- Updated RunnableWrapperExample with longer delays (200ms) for better reliability
- Examples remain clean with only metadata and Create(example: true)

Note: RunnableWrapperExample intentionally doesn't quit on Esc key (tests timeout handling)
Tests need additional work to properly coordinate key injection with example mode.
