add "Related" field to mechanisms

this could be a simple list- "link to another record" field in airtable. 

or there could be some more semantics to it, like three lists: one for "superior patterns", "subpatterens", "similar patterns"

example: Bonding Curve Token
Relations:
- Superior patterns: "Curation Markets"
- Subpatterns: "Token"
- Similar Patterns: "AMM"
