Release v22.73.0

Added

• [ReadModel(RequireQueryAttribute = true)] lets a read model expose only methods marked [Query], keeping reduction methods and private, internal or public helpers out of its endpoints and generated proxies. The setting defaults to false, preserving existing conventional query discovery. Adding [Query] alone does not change discovery of sibling methods. (#3163)
• ARC0026 and runtime validation report invalid query markers and ambiguous selected query names. Unmarked helpers on an opted-in read model are not subject to query-signature diagnostics. (#3163)
• ARCCHR0019 warns when a conventional read model contains a likely event-fold method that would become a query. Its previewable code fix opts the type into marked queries, supports editable partial declarations, and refuses migrations that would introduce compilation errors or require editing generated declarations. (#3163)

Fixed

• Proxy generation consistently selects one image per assembly identity when application and framework directories contain different copies, and ignores optional native runtime images without hiding invalid required managed inputs. (#3163)
