Changes

Bug fix: combinator type support in ArrayEditor

The TypeDropdown in the array item editor was passing SchemaEditorType (which includes "anyOf", "oneOf", "allOf") directly as the type field of a JSON Schema object. This caused a TypeScript error because type only accepts primitive JSON Schema types.

The onChange handler now mirrors the logic already used in SchemaPropertyEditor: when a combinator type is selected, it builds the appropriate anyOf/oneOf/allOf structure instead of setting type directly.

Before:

onChange={(newType) => {
  handleItemSchemaChange({
    ...withObjectSchema(itemsSchema, (s) => s, {}),
    type: newType, // TS error: "allOf" is not assignable to SchemaType
  });
}}

After:

onChange={(newType: SchemaEditorType) => {
  if (newType === "anyOf" || newType === "oneOf" || newType === "allOf") {
    const { type: _type, anyOf: _a, oneOf: _o, allOf: _al, ...rest } = asObjectSchema(itemsSchema);
    const initial = newType === "allOf"
      ? { allOf: [{ type: "object" as const }] }
      : { [newType]: [{ type: "string" as const }, { type: "number" as const }] };
    handleItemSchemaChange({ ...rest, ...initial });
  } else {
    const { anyOf: _a, oneOf: _o, allOf: _al, ...rest } = asObjectSchema(itemsSchema);
    handleItemSchemaChange({ ...rest, type: newType });
  }
}}

README updates

• Added anyOf/oneOf/allOf combinator support and additionalProperties to the Features section
• Added a "Combinator Schemas" subsection under Project Architecture
