Summary

Generates a Cratis Screenplay .play document from the source of an Arc application.

Added

Cratis.Arc.Screenplay package that generates a Screenplay .play document describing an Arc application - concepts, policies, modules, features and slices, with the commands, events, queries, projections, reactors, constraints and screens in each
Generation from source rather than from a running application, so a .play file can be produced from a checkout and regenerated in CI
Generation from a Roslyn Compilation, so the package can be driven from a CLI, an MSBuild task or a source generator
Diagnostics naming any construct that has no Screenplay counterpart, and where it was found
Model-bound [ChildrenFrom] and [Nested] projections are recovered, matching what the fluent form already produced (#2385)
Named authorization policies are recovered, with their requirements read from AddPolicy registrations where those can be read (#2386)
Aggregate roots are followed from the command that reaches them, so a handler that mutates an aggregate states the events it produces
Screens are declared for the component beside each slice
