holds() for postgres, mssql, mongodb, minio, lavinmq, mosquitto, mailu
and gitea, so the harness makes again a login the backend lost (hq issue
120). Each checks the mesh's password as the consumer presents it, or
compares it read-only, and returns false only when the backend says the
credential is absent or wrong; an unreachable backend throws.
Email server. Users/aliases/domains over the admin REST API, mail read via
doveadm in the imap container; ten tools. Emits user/alias created/deleted by
polling and diffing the admin API, so a change in the web admin is announced
as readily as one via a tool. Consumes nothing — deliberately, since mutating
mail accounts off another module's event could silently lose mail. Typechecks
against the sdk; manifest parses.
