Find outdated Webflow CMS items and decide what to archive

**Objective:** Find items in the Webflow CMS collection named `{collection-name}` that have not been updated in `{stale-days}` days (default 180), and recommend whether each should be refreshed or archived.

**Step 1: Resolve the collection**

Call `webflow-get-collection` with `display-name` set to `{collection-name}`, falling back to `display-name.contains`. If more than one collection matches, list them and stop. If none match, say so and stop.

**Step 2: Read the stale items**

Work out the cutoff date as today minus `{stale-days}` days. Call `webflow-get-collection-item` with the collection-id, `last-updated.to` set to the cutoff date, `archived` set to false and `draft` set to false, so only live items are considered.

**Step 3: Assess**

For each item, note its age since last-updated. Look through field-data for anything that dates the content (a date field in the past, a year in the name, an expired event or offer) and use it to lean the recommendation towards Archive; otherwise recommend Review.

**Step 4: Report**

One summary line with the cutoff date and the number of stale items. Then a table with columns Item name, Item ID, Last updated, Days since update, Evidence, Recommendation (Archive or Review), oldest first.

**Rules & Guidelines:**

* This is read-only. Use only `webflow-get-collection` and `webflow-get-collection-item`. There is no tool to archive or edit items; leave that to the user.
* Age alone is not a reason to archive. Evergreen content such as team members or product pages can be old and correct; recommend Review for those.

**Validation:**

* If no items are older than the cutoff, say the collection is up to date.
* If the collection has no live items at all, say so.
