fix(test): patch vitest resolver (#356)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Patches Vitest resolver and test build to resolve package aliases directly, aligns browser context/provider exports, and fixes type/module augmentations.
> 
> - **Test build (`packages/test/build.ts`)**:
>   - Patch `VitestCoreResolver` to resolve `@voidzero-dev/vite-plus/test` and `@voidzero-dev/vite-plus-test` directly to `dist/index.js`, with subpath routing to `vitest/*`.
>   - Add patches for module augmentations (`global.d.*.d.ts` -> relative paths), Chai type reference in `@vitest/expect/index.d.ts`, and mocker `hoistedModule` to accept package aliases.
>   - Expand optimizeDeps exclude list and inject vendor-aliases handling for vitest/browser and aliases.
>   - Create browser entry files and context/type wiring; copy/update browser client files and vendor stubs.
> - **Exports and shims**:
>   - Route `./context` and `./browser/context` to `./dist/@vitest/browser/context.js` (preserve single module identity).
>   - Add `./browser/providers/{playwright,webdriverio,preview}` subpath exports in both `packages/test` and `packages/cli`.
>   - CLI `build.ts`: `.d.ts` shims now include side-effect import before `export *` to keep module augmentations.
> - **Dependencies**:
>   - Add `@types/chai` to test package; add `playwright` as a root devDependency.
