List emails received in a date range: metadata + snippet, oldest-first, capped at 500 with no truncation flag. Spam and trash are excluded. Mail sent from the mailbox itself (i.e. the team's replies) is excluded unless include_sent is true. Each result has a jump_url deep link that opens the email for anyone signed into the mailbox. Use read_email for the full body.

Read one email by id (from list_emails): full headers and body text (HTML converted to text, capped at 50k chars).
