Match Bugsnag collaborators to Azure DevOps users

**Objective:** For Bugsnag project {project-name}, match each collaborator to an Azure DevOps user by email, and optionally limit the Azure DevOps side to team {team-name}.

**Step 1: List collaborators (Bugsnag)**

Call `bugsnag-get-project-collaborator` with `project-name` and `max-records` 100. Note `collaborator-name`, email and administrator for each. If none, stop.

**Step 2: Look each one up (Azure DevOps)**

For each collaborator call `azure-devops-get-user` with `mail-address` set to the email. If nothing, try `display-name.contains` with the collaborator name. When {team-name} is given, also call `azure-devops-get-team-member` with `team-name` and note whether the person is a member.

**Step 3: Report**

A table: collaborator, email, matched Azure DevOps display-name and principal-name, match basis (email or name), team membership if checked. Then list collaborators with no match and Azure DevOps team members with no Bugsnag account.

**Rules & Guidelines:**

* Tools prefixed azure-devops are on the Azure DevOps server; tools prefixed bugsnag are on the Bugsnag server. Both must be connected.
* Read-only job. Never call `bugsnag-link-error-issue`, `bugsnag-create-error-issue`, `bugsnag-assign-error`, `bugsnag-fix-error`, `bugsnag-ignore-error`, `bugsnag-discard-error`, `bugsnag-open-error`, `bugsnag-update-error-severity`, `bugsnag-update-project`, `bugsnag-add-project` or `bugsnag-add-project-collaborator`. The Azure DevOps server has no write tools.

**Validation:**

* A name-only match is low confidence; label it and never treat it as an email match.
* If two Azure DevOps users match one collaborator, list both and do not choose.
