Release v7.27.2

Added

• The authoring workflow now previews an edited model's render with cratis render --check (CLI 3.44.0: exit 0 current, 6 changes pending, 5 refused) and reads the receipt's sources and bySource (CLI 3.45.0) and MCP semantic-diff (Screenplay 4.131.0) to confirm an edit changed only what it should. They are labeled published, not executed on the verified vector. (part of #536)
• The UI composition contract explains what Scene 4.17 does with an authored destination: nested core:outlet composition with deep links and innermost back, toolbar buttons that open a dialog or slice screen, the SettingsPage template and the embedded WebViewPackageHost. (part of #536)
• Routing evaluations cover a build, edit and run request for a whole business application. (part of #536)

Changed

• The screens guidance separates the executed vector (CLI 3.43.0, Stage 4.52.0, Scene 4.15.0) from packages published since (Scene 4.17.0, Screenplay 4.133.1, Stage 4.64.0, CLI 3.46.1, Studio 0.152.2), and no longer calls the newer ones the verified latest. (part of #536)
