Release v4.71.0

Added

• Rendered read-model and query specifications whose givens are routed now render and run, where they used to be refused with STAGE-ESM-030. Each given is seeded on its own event source, stream type and stream identity through ReadModelScenario, so a reducer filtered to a source or stream replays exactly the facts it would see in production. (#327)
• A navigation contribution's group is carried into the Scene output. (#327)

Changed

• Stage now builds against Screenplay 4.133.3 and Chronicle 19.45.0, and the Stage Host image runs cratis/chronicle:19.45.0-development. (#327)
• Generated applications pin Cratis and Arc 22.68.0, an explicit Cratis.Chronicle 19.45.0 client and a cratis/chronicle:19.45.0-development kernel image. Apart from those version strings the scaffold is unchanged. (#327)
• Generated read-model and query specifications dispose their ReadModelScenario, which is disposable from Chronicle 19.45.0, so generated applications keep building warning-free. (#327)
• A navigation contribution that sets id, icon, presentation or a destination is refused with STAGE-SCENE-UI-001, naming the field, because the pinned Scene runtime does not honor it yet. Rendering these fields is tracked in #329. (#327)
