Release v3.18.0

Added

• cratis render reads the implementation files a model references (file ... on policies, validation, reducers and other code) from the model folder, or from a single .play file's folder, and gives their contents to the Screenplay compiler, so file-backed code is identified by content. (#184)
• A file the loader refuses (outside the model folder, a link, missing, too large or not text) is reported as PLAY0430–PLAY0434, even when compilation fails. (#184)

Changed

• cratis render passes the model's implementation requirements and resolved code to Stage, so a missing or changed body stops rendering with STAGE-ESM-020 and the loader's reason. (#184)
• The CLI now bundles Screenplay 4.32.0 and Stage 4.17.0, and cratis run defaults to the matching cratis/stage:4.17.0 image.
• The render and run reference recommends a dedicated folder for models with file attachments: a single-file cratis run mounts only the .play file.
