OpenAPI Diff for DSH

Structural OpenAPI JSON breaking-change check: removed paths/methods/params/properties/responses, new required fields, parameter-became-required, type changes.

Use

node bin/dsh-openapi-diff.mjs old.json new.json
node bin/dsh-openapi-diff.mjs old.json new.json --json

In DSH:

Use openapi_diff with old=old.json new=new.json.

Limits

• JSON only
• Structural subset; no full $ref resolution or oneOf/allOf semantics
• Not a behavioral compatibility test or contract test
• A clean result is not a compatibility proof
