Gmail whoami (signed-in account)
Report which Gmail account this browser is signed in as: display name and email, from Gmail's account switcher. Being signed out is reported as a normal answer (loggedIn false), not an error, so it can be used to check a session before running other Gmail scripts.

Search Gmail
Search the signed-in Gmail with the native query syntax (from:, to:, subject:, has:attachment, after:/before:, labels…) and return matching threads: threadId (feed it to get_thread / reply_to_email), sender, senderEmail, subject, snippet, date, unread, starred, hasAttachment. Results are threads rather than individual messages, which is Gmail's own search granularity, and only the first page of results is returned (up to 50).
Send Gmail email
Send an email from the signed-in Gmail account, with a plain-text body and an optional single file attachment.
Get Gmail thread
Read a Gmail thread by its hex threadId (as returned by search_emails): subject plus every rendered message's from, fromEmail, to, date, plain-text body and attachment names. In long threads Gmail collapses older messages, so only rendered (expanded) messages are returned.
