Fix variable definition test to detect set_fact and ansible.builtin.set_fact (both block and inline forms)
- Support fully qualified ansible.builtin.set_fact
- Parse inline set_fact mappings (e.g. set_fact: { a: 1, b: 2 })
- Continue scanning inside vars/set_fact blocks for Jinja {% set %}, {% for %}, and {% macro %}
- Ensures variables defined by set_fact are correctly recognized as defined
