Added

• Cratis.Showrunner.GuestList.Authoring, the operator side of audiences, which works without Direct: the GrantAudience and WithdrawAudience commands for a tenant, a user or the system, the ProductGuestList and UndeclaredAudienceGrant queries, and an outbox reactor that publishes AudienceGranted and AudienceWithdrawn once, in the order they were decided (Operator side: commands and API to grant and withdraw audiences #126)
• Commands refuse a missing product, an invalid audience name, a tenant or user a level does not need or does not name, and an unknown tenant (through the optional IKnownTenants); granting a held audience or withdrawing one that is not held records nothing
• AddGuestListAuthoring with AddressToProducts and DeclaredAudiences options, and GuestListAuthoring.Policy for the host's authorization
• Integration specifications that run an operator store and a product store against a real Chronicle kernel
• A guide to granting audiences as an operator, and GuestList in the audience routing table
