gmail.search_messages()

Provider-native Gmail search over messages using the messages.list `q` parameter. Accepts standard Gmail search syntax (for example `from:`, `subject:`, `newer_than:`, `has:attachment`). Returns message and thread IDs only; query `message_details` by `id` for headers, payload, or raw content.
