Release v3.84.0

Changed

• Bundles Stage 4.174.0 (from 4.167.1); cratis run starts cratis/stage:4.174.0 by default, and cratis render plans with the same renderer. The renderer now renders models whose generated C# names collide (a command property named like its command, a query named like its read model or a property of it) by escaping the colliding member with a trailing _ and reporting it as STAGE-ESM-050, instead of refusing them with STAGE-ESM-012. It also renders read models with composite keys, scalar absence assertions (then no <ReadModel> <key>), per-run projections with optional scalar properties, per-production event source and stream overrides, and live (observable) queries that push updates to the generated frontend.
