Find Chargebee customers missing from PowerGP Online

**Objective:** Find Chargebee customers that have no matching PowerGP customer, or the reverse, for the first {max-customers} customers (default 50), optionally limited to Chargebee company names containing {name-filter}.

**Step 1: List Chargebee customers**

Call `chargebee-get-customer` (chargebee) with `max-records` set to the limit and `company.contains` set to the filter if given. Record `id`, `company`, `first-name`, `last-name`, `email`.

**Step 2: Look each one up in PowerGP**

For each, call `powergp-online-get-customers` (powergp-online-ai) with `customer-name.contains` set to `company` (or the full name when company is empty). Record `customer-number` and `customer-name`. Treat names equal after ignoring case, punctuation and suffixes such as Inc or LLC as a match. If several PowerGP customers match, mark it ambiguous and list them.

**Step 3: Report**

Three lists: matched (Chargebee id to PowerGP customer-number), in Chargebee only, and ambiguous. State the counts.

**Rules & Guidelines:**

* Tools prefixed powergp-online- belong to the powergp-online-ai server; tools prefixed chargebee- belong to the chargebee server. Both servers must be connected.
* Read-only: call only the get tools named above. Never create, change or delete anything in either system.
* Never print card or bank details; report ids, names and amounts only.

**Validation:**

* If Chargebee returns nothing, stop and say so.
* Match on name only as a suggestion; flag every match as name-based and unconfirmed.
