Check Attio meeting attendees against Granola

**Objective:** Compare the participants Attio lists for the meeting `{meeting-title}` with the attendees Granola recorded, and report who is missing on either side.

**Step 1: Attio participants**

Call `attio-get-meeting` (Attio server) with `title.contains` set to `{meeting-title}`. If several meetings match, list them and stop. Then call `attio-get-meeting-participant` (Attio server) with `meeting-id` set to the matched meeting id. Record each participant's name and email address.

**Step 2: Granola attendees**

Call `granola-get-note` (Granola server) with `title.contains` set to `{meeting-title}` and take the note id. Then call `granola-get-attendee` (Granola server) with `note-id` set to that id, and `granola-get-invitee` (Granola server) with the same `note-id`. Record name and email for each.

**Step 3: Match**

Match people by email address, case-insensitive. Where an email is missing on one side, fall back to an exact name match and flag it as a weaker match.

**Step 4: Report**

Three lists: in both systems, only in Attio, only in Granola. Add `{include-invitees}` handling: if it is yes, also mark people who were invited in Granola but did not attend (default no).

**Rules & Guidelines:**

* Attio tools: `attio-get-meeting`, `attio-get-meeting-participant`. Granola tools: `granola-get-note`, `granola-get-attendee`, `granola-get-invitee`.
* Read-only. Do not call `attio-add-person`, `attio-update-person`, `attio-upsert-person` or any delete tool.

**Validation:**

* If either side returns no meeting or note, report which side is empty and stop.
* Never merge two people on a name match alone without flagging it.
