`validateProperty` in `params.ts` did not handle the case where `items` is an array — the JSON Schema draft 07 tuple validation form. This caused false validation failures for schemas like Angular's `@angular/build:unit-test`, which uses tuple `items` to type reporter configurations: ```json { "type": "array", "minItems": 1, "maxItems": 2, "items": [ { "anyOf": [{ "type": "string" }, { "enum": ["junit", "html", ...] }] }, { "type": "object" } ] } ``` Options like `"reporters": [["junit", {"suiteName": "MyApp"}]]` would incorrectly fail validation with _"Property 'reporters' does not match the schema"_. ## Changes - **`validateProperty`**: when `schema.items` is an array, validates each element against its positional schema instead of passing the whole array as a schema - **`minItems`/`maxItems` enforcement**: array length is now validated against `minItems` and `maxItems` constraints when present - **`additionalItems` support**: rejects extra items when `additionalItems: false`; validates against the `additionalItems` schema when present; otherwise allows additional items (spec-compliant default) - **`PropertyDescription` type**: added `minItems`, `maxItems`, `additionalItems` fields; narrowed `items` from `any` to `PropertyDescription | PropertyDescription[]` - **Type guards**: added guards in `coerceType` and `getPromptsForSchema` where `items.enum` was accessed without accounting for the array form
