Spot HubSpot deals nobody has touched in weeks

**Objective:** List open deals in `{pipeline-name}` (default: every pipeline) that have had no logged activity for at least `{quiet-days}` days (default 21).

**Step 1: Open deals**

Call `hubspot-get-deals` (with `pipeline-name` = `{pipeline-name}` when given). Drop deals whose `deal-stage-name` is Closed won or Closed lost. If more than 50 open deals remain, take the 50 with the largest `amount` and say you did.

**Step 2: Last activity per deal**

For each open deal, using its `record-id`:

* Call `hubspot-get-notes` with `deal-id`.
* Call `hubspot-get-meetings` with `deal-id`.
* Call `hubspot-get-engagements` with `deal-ids.contains` = the record-id, which also covers calls, emails and tasks.

Take the latest date across all three as the deal's last activity. A deal with no activity at all counts as stalled since its `create-date`.

**Step 3: Report**

Table of stalled deals, sorted by amount descending: deal, stage, amount, close date, owner, last activity date, days quiet, what the last activity was. Then a short per-owner count of stalled deals and stalled value.

**Rules & Guidelines:**

* This prompt is read-only. Do NOT call any write tool: `hubspot-add-contact`, `hubspot-add-company`, `hubspot-add-deal`, `hubspot-add-ticket`, `hubspot-update-contact`, `hubspot-update-company`, `hubspot-update-deal`, `hubspot-update-ticket`, `hubspot-add-contact-note`, `hubspot-add-company-note`, `hubspot-add-deal-note`, `hubspot-add-ticket-note`.
* Do not count the deal's own create or update as activity.

**Validation:**

* If there are no open deals, say so and stop.
* If no deal is stalled, say so and give the longest-quiet deal anyway.
