Tag newly won Capsule CRM customers in Drip

**Objective:** For Capsule CRM opportunities at the Won milestone that closed in the last `{lookback-days}` days (default 30), apply the Drip tag `{drip-tag}` (default Customer) to the people on them who are already Drip subscribers.

**Step 1: Find recently won opportunities**

Call `capsule-crm-get-opportunity` with `milestone-name` set to Won and `closed-on-date.from` set to `{lookback-days}` days before today. Keep `name`, `party-name`, `party-organization-name`, `value` and `closed-on-date`.

**Step 2: Get the contacts' emails**

For each opportunity, call `capsule-crm-get-party` with `name` set to its `party-name`. If that party is an organization (`type`), also call `capsule-crm-get-party` with `organization-name.contains` set to the organization's name to get the people who work there. Keep every person's `email`. Skip parties with no email.

**Step 3: Keep only existing, active Drip subscribers**

For each email, call `drip-get-subscriber` with `email` set to it. Keep only people whose Drip `status` is active and whose `tags` do not already include `{drip-tag}`. Do not tag anyone who is not already in Drip or who is unsubscribed.

**Step 4: Confirm, then tag**

Show a table: email, Drip name, the won opportunity, its value and close date. Ask the user to confirm. Do not tag anyone until they say yes.

After confirmation, for each row call `drip-add-subscriber-tag` once with `email` set to the subscriber's email and `tag` set to `{drip-tag}` (default Customer).

**Step 5: Report**

People tagged, people already tagged, and won contacts who are not Drip subscribers (listed, not added).

**Rules & Guidelines:**

* Tools whose names start with drip- are on the drip MCP server; tools whose names start with capsule-crm- are on the capsule-crm MCP server. If either set is missing, stop and say which server is not connected.
* Match people across the two systems by email address only, compared case-insensitively after trimming spaces. Never match on name alone.
* The only tool that may write is `drip-add-subscriber-tag`, once per confirmed person.
* Never add a person to Drip: `drip-add-subscriber` and `drip-add-subscriber-to-campaign` would create subscribers without their consent.
* Do NOT call these Drip tools: `drip-add-subscriber`, `drip-update-subscriber`, `drip-remove-subscriber-tag`, `drip-add-subscriber-to-campaign`, `drip-remove-subscriber-from-campaign`, `drip-remove-subscriber-from-all-campaigns`, `drip-unsubscribe-subscriber`, `drip-start-subscriber-workflow`, `drip-remove-subscriber-from-workflow`, `drip-activate-campaign`, `drip-pause-campaign`, `drip-activate-workflow`, `drip-pause-workflow`.
* Do NOT call these Capsule CRM tools: `capsule-crm-add-party`, `capsule-crm-update-party`, `capsule-crm-add-note`, `capsule-crm-update-note`, `capsule-crm-add-task`, `capsule-crm-update-task`, `capsule-crm-add-opportunity`, `capsule-crm-update-opportunity`, `capsule-crm-add-case`, `capsule-crm-update-case`.

**Validation:**

* If there are no won opportunities in the window, say so and stop.
* If `drip-add-subscriber-tag` fails for one person, report the error and carry on with the rest.
