Subject: [PATCH] Improve loading error messages with item context and
 hierarchy path

Add item_load_context() context manager to tum_except.py that enriches
ETUMSyntaxError with the item type, name, and parent path instead of
replacing the original message with a vague 'missing or wrong parameter'.
