// The betterbird module's Go tools bundle (novox/hq ADR 0188, ADR 0193, ADR 0208): Betterbird, the
// mail and calendar client, in the operator's session, served by the node's runtime as the operator
// account. The module holds no seat, so every tool is its own.
//
// The operator's mail, calendars, accounts and credentials are never read: a tool reads processes,
// profiles.ini, and of the profile only prefs.js, user.js and extensions.json, and answers no
// preference that can hold a credential or names an account.
