+
+### Patch Changes
+
+- 5fc2359: Enable oxfmt import sorting (the `.oxfmtrc.json` used a key oxfmt 0.58 dropped, so sorting was silently off) and adopt the shared `@btravstack/lefthook` hooks preset.
+- 74433ea: Consume the shared `@btravstack/tsconfig` / `@btravstack/typedoc` published config directly (the local `tools/*` packages are removed). Also add a direct `@types/node` dev dependency to `@temporal-contract/contract` (its siblings already declare it) so `types: ["node"]` still resolves now that the strict TS base comes from `node_modules/@btravstack/tsconfig`.
