See which Chorus donor calls were followed by Bloomerang gifts

**Objective:** For Chorus conversations in the last `{lookback-days}` days (default 90), optionally only those owned by the Chorus user `{rep-email}` (if empty, every user), report which participating donors made a Bloomerang gift within `{attribution-days}` days after the conversation (default 30).

**Step 1: List the conversations in Chorus**

Call `chorus-get-engagements` with `date.from` set to the start of the window, `max-records` 50, and `user-email` `{rep-email}` if given. If the result is capped, say so.

**Step 2: Match participants to constituents**

For each conversation, call `chorus-get-conversation-participants` with its `conversation-id` and keep external participants (no `user-id`, not typed as internal). Match each email with `bloomerang-get-email-address` (`value`) to get `account-id`, caching each email's result.

**Step 3: Read the gifts that followed**

For each conversation and matched account id, call `bloomerang-get-transaction` with `account-id`, `date.from` the conversation date and `date.to` the conversation date plus the attribution window. Exclude transactions where `refunded` is true.

**Step 4: Report**

1. **Per Chorus owner** (`user-name`): conversations with donors, distinct donors reached, donors who gave afterwards, total given afterwards.
2. **Gift detail**: conversation date, subject, owner, donor, gift date, amount, method.
3. **Donors spoken to who have not given** in the window, sorted by their Bloomerang `engagement-score` from `bloomerang-get-constituent` (`id` the account id), highest first, at most 10.

State plainly that a gift following a conversation is a correlation, not proof the conversation caused it.

**Rules & Guidelines:**

* Tools whose names start with chorus are on the chorus server; tools whose names start with bloomerang are on the bloomerang server.
* This prompt is read-only. Do not call `bloomerang-add-transaction`, `bloomerang-add-task`, `bloomerang-add-interaction` or any other Bloomerang add or update tool, and do not call any Chorus action such as `chorus-add-moment`.
* Count a gift once even if the donor had several conversations before it; attribute it to the most recent conversation.

**Validation:**

* If no participant matches a constituent, say so and stop.
* Chorus dates carry a time; compare by calendar day. Match emails case-insensitively.
