Catch HubSpot wins that never got billed in Stripe

**Objective:** Find HubSpot deals closed won in the last `{closed-since-days}` days (default 60) whose company has no Stripe customer or no live Stripe subscription, so billing gaps after a sale are caught.

**Step 1: Find closed won deals in HubSpot**

Call `hubspot-get-deal-pipeline-stages` to learn the exact closed won stage label(s). Then call `hubspot-get-deals` with `deal-stage-name` = each closed won label and `close-date.from` = today minus `{closed-since-days}` days (default 60), `max-records` 200. If `{pipeline}` is given, also pass it as `pipeline-name`.

If no deals come back, say so and stop.

**Step 2: Get the buyer's emails and domain in HubSpot**

For each deal's `company-id`, call `hubspot-get-companies` with `record-id` = that id to get `domain`, and `hubspot-get-contacts` with `company-id` to get contact emails. If the deal has no company but has a `contact-id`, call `hubspot-get-contacts` with `record-id` = that id.

**Step 3: Look for the customer and subscription in Stripe**

Call `stripe-get-customer` with `email.contains` = the company domain (skip free mail domains), then with `email` = each contact email not yet matched. If no customer matches, classify the deal as "No Stripe customer".

For each matched `customer-id`, call `stripe-get-subscription` with `customer-id`. If none has status active or trialing, classify as "Customer but no live subscription". Otherwise classify as "Billing in place" and compare the deal `amount` with the subscription's annualised value from `stripe-get-subscription-item` (MRR x 12).

**Step 4: Report**

1. No Stripe customer: deal name, company, close date, amount, deal owner.
2. Customer but no live subscription: as above plus Stripe customer-id and subscription statuses seen.
3. Billing in place but annualised value differs from the deal amount by more than 10 percent: deal amount, annualised Stripe value, difference.
4. Count of deals with billing in place and matching.

**Rules & Guidelines:**

* `hubspot-get-deal-pipeline-stages`, `hubspot-get-deals`, `hubspot-get-companies` and `hubspot-get-contacts` are on the hubspot server. `stripe-get-customer`, `stripe-get-subscription` and `stripe-get-subscription-item` are on the stripe server.
* Read-only. Do not call `hubspot-update-deal`, `hubspot-add-deal-note` or any other HubSpot add or update tool.
* A deal may legitimately be one-time (no subscription). If the deal's `deal-type` or name suggests a one-off service, say so instead of flagging it as a gap.

**Validation:**

* Match on email and domain only, never on company name alone.
* If the deal closed in the last 3 days, mark it "recent, may not be billed yet".
* If a parameter is empty, use its default; ignore `{pipeline}` when empty.
