Find Drip subscribers who never reached OnePageCRM

**Objective:** Find subscribers in Drip account `{drip-account}` (created since `{created-since}` if given, up to `{max-subscribers}`, default 50) that do not exist as OnePageCRM contacts.

**Step 1: Read subscribers from Drip**

Call `drip-get-subscriber` with company `{drip-account}`, created-date.from `{created-since}` if given, and max-records `{max-subscribers}`. Keep email, first-name, last-name, status, lead-score, tags.

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

For each subscriber call `onepagecrm-get-contact` with email set to the subscriber email. No result means the subscriber is missing from the CRM.

**Step 3: Report**

A table of missing subscribers (email, name, lead-score, tags, created-date) sorted by lead-score descending, then a count of matched ones.

**Rules & Guidelines:**

* OnePageCRM tools are `onepagecrm-*`; Drip tools are `drip-*`. Both servers must be connected.
* This prompt is read-only. Never call any `onepagecrm-add-*`, `onepagecrm-update-*`, `onepagecrm-delete-*` tool, nor any Drip tool that adds, updates, removes, pauses, activates or unsubscribes.
* Match on email, case-insensitive and trimmed. Never match on name alone.

**Validation:**

* If Drip returns nothing, stop and say so.
* Subscribers with no email cannot be matched; list them separately.
