Bump to 0.9.1 and record the toolchain update

 - **MINOR** — new venues, NPC archetypes, systems, or features that are backward compatible.
 - **PATCH** — bug fixes and small polish that do not change behavior.
 
-The single source of truth for the version is `config/version` in `project.godot` (currently `0.9.0`). Each release is tagged in git as `v<version>` (e.g. `v0.6.0`). The `0.x` series is pre-1.0, so MINOR bumps may introduce breaking changes while the prototype is still stabilizing. `tools/build_releases.sh` and `tools/publish_release.sh` read the version from `project.godot`, so bumping it there is the only required step before a release. The full bump checklist lives in [`RELEASING.md`](RELEASING.md).
