Spot duplicate companies in Attio before they split your data

**Objective:** Find likely duplicate company records in Attio, optionally limited to names containing `{name-contains}`.

**Step 1: Pull companies**

Call `attio-get-record-companies` with `max-records` 200. If `{name-contains}` is given, pass it as `name.contains`.

**Step 2: Detect duplicates**

* Group by identical `domains`. Any group of two or more is a likely duplicate.
* Group by name after lowercasing and removing Inc, Ltd, LLC, GmbH and punctuation.
* For each group, call `attio-get-record-deals` with `associated-company` set to each company name and `attio-get-record-people` with `company` set likewise, to count what hangs off each record.

**Step 3: Report**

For each group: the record ids, names, domains, created dates, number of people and deals on each, and a recommended survivor (the one with the most linked data, then the oldest). Say what would have to be moved before deleting the others.

**Rules & Guidelines:**

* This prompt is read-only. Never call `attio-delete-company` or `attio-update-company`. Recommend only; to act, the user should run the delete prompt.
* Do not treat two companies as duplicates on name alone if their domains differ. Mark them as possible.

**Validation:**

* If no duplicates are found, say so.
* State that the sample is capped at 200 companies.
