Same mistake as the original implementer wave — used the deprecated
groups_id field name on res.users in the search domain. Odoo 19 raises
ValueError: Invalid field res.users.groups_id. Should be group_ids.
CLAUDE.md rule 13l example also fixed so future-Claude doesn't copy
the bug from the documentation.
