Limit the fallback to unsupported-argument errors.

When args.display_mode is set and plugin_instance.display() raises an internal TypeError, the fallback calls display(force_clear=True) again. This can duplicate side effects and hide the original error. Re-raise errors that do not indicate an unexpected display_mode keyword.

In `@scripts/render_plugin.py` at line 158, Update the TypeError handling around
plugin_instance.display() so the fallback to display(force_clear=True) occurs
only when the exception indicates an unsupported display_mode argument; re-raise
all other TypeError instances to preserve internal errors and avoid duplicate
side effects.
