v1.7.0

Added

• email_batch_label tool — add/remove Gmail labels on multiple emails in one call, using a single native batchModify request instead of one email_label call per message. Falls back to sequential per-message calls only if the batch request itself fails. Matches the existing email_batch_move/email_batch_mark/email_batch_delete pattern; Gmail-only, same as email_label.

Fixed

• email_folder_create silently dropped parentPath on Gmail — a call like { name: "Anthropic", parentPath: "Tech" } reported success but created a flat "Anthropic" label instead of the nested "Tech/Anthropic". Gmail has no real folder hierarchy; nesting is just a /-delimited label name, and the Gmail adapter's createFolder never read its own parentPath argument (Outlook and IMAP already handled this correctly). Now builds the full parentPath/name label name before creating it.
