add "Related" field to mechanisms

[orishim]

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"
