feat(jsonschema): JSON Schema type inference v1

[TizzySaurus]

• Add preliminary type inference for jsonSchemaToType
• Fix incorrect parsing behaviour where prefixItems is specified with items as an array (f405773)

  jsonSchemaToType({
    type: "array",
    prefixItems: [{type: "string"}, {type: "number"}],
    items: [{type: "boolean"}]
  });
  
  // Runtime logic before: [string, number, ...boolean[]]
  // Runtime logic after: [string, number, boolean]

  • ✅ properties
  • ✅ required
  • ⚠️ additionalProperties (get typed as unknown)
  • ⚠️ patternProperties (get typed as unknown)
