Add visualization for compound molecules (those created by bonding protos):
- Detect compound molecules via IsCompound() check on root issue
- Display "Bonded from:" section showing constituent protos with bond types
- Show bond point when specified (attachment site within molecule)
- Format bond types as human-readable: sequential, parallel, on-failure, root
- Include is_compound and bonded_from in JSON output
Example output for compound molecules:
🧪 Compound: proto-feature-with-tests
ID: bd-abc123
Steps: 5
🔗 Bonded from:
├── proto-feature (sequential)
└── proto-testing (sequential, at step-2)
Added unit tests for compound detection and bond type formatting.
