Four new tests covering the bug where only belongs_to/related_to were
recognized while Has, Topics, Events, Notes, Owner, etc. were missed:
- Many generic field types populate the relationships HashMap
- Single wikilink strings vs arrays both parse correctly
- All SKIP_KEYS (Is A, aliases, status, cadence, etc.) are excluded
- Mixed arrays with wikilinks and plain strings keep only wikilinks
