"""SaaS connectors: Google Drive, OneDrive, SharePoint, Dropbox, Notion,
Confluence Cloud, Slack, Microsoft Teams, GitLab and email (IMAP).

Every connector lists items with a stable ``external_id`` and a ``version``
hint (vendor content hash, etag, revision or edit time) so incremental syncs
only fetch what changed, pages through the vendor API up to ``max_items``, and

``site_url``, IMAP ``host``) pass the SSRF guard. OAuth tokens come from
``app.connectors.oauth``
