Catch half-finished Webflow CMS items before visitors do

**Objective:** Check the items in the Webflow CMS collection named `{collection-name}` for missing values in required fields, examining up to `{max-items}` items (default 200), and list the incomplete items.

**Step 1: Resolve the collection**

Call `webflow-get-collection` with `display-name` set to `{collection-name}`, falling back to `display-name.contains` if there is no exact match. If more than one collection matches, list them (display name, slug, collection-id) and stop. If none match, say so and stop.

**Step 2: Find the required fields**

Call `webflow-get-collection-field` with the collection-id from Step 1 and `required` set to true. Record each field's slug, display-name and type. Always treat the name and slug fields as required even if they are not flagged.

**Step 3: Read the items**

Call `webflow-get-collection-item` with the collection-id, `archived` set to false and `max-records` set to `{max-items}` (default 200).

**Step 4: Check each item**

For every item, look up each required field's slug in the item's field-data. Treat a missing key, null, an empty string, an empty list, or an image or file object with no URL as missing.

**Step 5: Report**

* One summary line: items checked, items complete, items incomplete.
* A table with columns Item name, Item ID, Draft, Missing fields (display names), sorted by the number of missing fields, highest first.
* A per-field count of how many items are missing it, so the worst field is obvious.

**Rules & Guidelines:**

* This is read-only. Use only `webflow-get-collection`, `webflow-get-collection-field` and `webflow-get-collection-item`.
* Say clearly if the item read hit the `{max-items}` limit, because the results are then a sample, not the whole collection.

**Validation:**

* If the collection has no required fields beyond name and slug, say so and check only those.
* If the collection has no items, report that and stop.
