Give the assistant Drive access so it can manage automatic attachment sorting

Problem

Automatic attachment sorting into Drive is great, but the normal assistant agent has no Drive access. When I ask it in chat to change how my attachments are being filed (for example, moving a document type to a different folder), it can't see or modify the filing setup, so adjustments can't be made conversationally.

Suggested solution

Expose Drive / document filing tools to the assistant, similar to the existing label, folder, and rule tools, so it can:

• inspect the current Drive connection and attachment filing configuration
• adjust the sorting from chat (e.g. "from now on, put invoices in Finance/Invoices")

Context

The assistant already manages rules, labels, folders, and settings through chat tools, so this feels like a natural extension of that set.
