feat(validator): detect broken/malformed workflow connections (#620)

Browse Source 
Add comprehensive connection validation: unknown output keys with fix
suggestions, invalid type field detection, output/input index bounds
checking, and BFS-based trigger reachability analysis replacing simple
orphan detection.
