### 📝 Notable tsconfig behavior changes

These ship via the `oxc_resolver` 11.21.3 bump (#9841) and affect `resolve.tsconfigPaths` (Vite 8 resolves through oxc-resolver):

- **Honor explicit non-TS extensions in `include`** (oxc-project/oxc-resolver#1213). `compilerOptions.paths` now resolve for importers whose extension is explicitly listed in a tsconfig's `include` (e.g. `src/**/*.vue`, `src/**/*.svelte`). Previously oxc-resolver filtered importers by extension before evaluating the `include` globs, so a `.vue`/`.svelte` file listed in `include` never matched its project and its `paths` were skipped. This unblocks the default create-vite Vue + TS layout (a solution-style root plus a referenced `tsconfig.app.json` that declares `paths` and `include: ["src/**/*.ts", "src/**/*.vue"]`). Matches vue-tsc and svelte-check, which register these extensions via TypeScript's `extraFileExtensions`.
- **No fallback to the outermost tsconfig in auto-discovery** (oxc-project/oxc-resolver#1220). Auto-discovery no longer attaches the topmost ancestor `tsconfig.json` to a file that no project actually owns (via `files` / `include` / project references). Previously such a file inherited the outermost ancestor's `paths` / `baseUrl`, leaking aliases into files that project does not own. oxc-resolver now returns no config in that case, matching tsserver / typescript-go, which route such files to an inferred project with no aliases.
