Release v3.42.0

Added

• cratis screenplay conform <MODEL_ROOT> checks that hand-written code still matches an authored Screenplay model: it extracts a model from the code with the same source adapters as cratis screenplay generate, without writing anything, and compares it with the model using Screenplay's own comparison (#259)
• Code elements missing from the model and event or member shape mismatches are reported as blocking drift; model elements not yet realized in code are reported as informational, since a model may legitimately be ahead of the code (#259)
• conform exits 0 when the code conforms, 1 on blocking drift and 2 when the check could not run or could not compare everything, and -o json gives machine-readable findings for CI (#259)

Changed

• The CLI bundles Screenplay 4.127.0 and reads executable models up to ESM v9; validate and the Screenplay MCP server admit v9 models (#302)
• cratis render refuses ESM v9 models with CLI-RENDER-004 until Stage can render public events (#302)
