Release v7.29.0

Changed

• The backend application profiles (cratis/application/csharp, typescript, elixir, kotlin, java, arc-chronicle, arc-only and chronicle-dotnet) now include the Screenplay method and language skills and the Screenplay MCP server, so model-first work can be proposed and done in application repositories. Installing them does not opt a repository in: that still takes a committed .play model under the model root or a configured mcpServers.screenplay.root, and with Cratis CLI 3.46.1 or later the server creates no model folder until the first write (#495)
• In Pi, when Screenplay comes in only through an application profile and no model root is configured, a missing Cratis CLI, a CLI older than 3.46.1 or a server that fails to start leaves the Screenplay tools inactive with one notice instead of an error; selecting cratis/screenplay (or a profile that already included it) or configuring a root keeps startup errors visible (#495)
