`GmailTools` has been extended with a broader set of email management functions and a new service account authentication path. Teams can now handle more of the Gmail workflow, including reading, drafting, sending, replying, labeling, and searching, directly from an agent, while platform teams gain a credential-free auth option suited for server-side and multi-user deployments.

Details**:**

- New tools cover the full email lifecycle: `get_emails_by_date`, `get_emails_by_thread`, `send_email_reply`, `create_draft_email`, `mark_email_as_read`, `mark_email_as_unread`, `list_custom_labels`, `apply_label`, `remove_label`, and `delete_custom_label`
- Service account authentication provides a governed, non-personal credential path for automated and multi-tenant workflows
- Existing OAuth credential flows (`creds`, `credentials_path`, `token_path`) continue to work with no migration required
- Use `include_tools` or `exclude_tools` to expose only the subset of tools your agent needs
