Pull request overview

Migrates the Stencil spec test setup in core/ from the legacy Jest-based runner to @stencil/vitest, updates Stencil core to a newer version, and adjusts unit tests/configuration accordingly (including a pnpm patch to improve ElementInternals mocking in mock-doc).

Changes:

• Replace stencil test --spec (Jest) with stencil-test (Vitest) and add Vitest config + setup shims.
• Update many spec tests from newSpecPage()/jest.* to @stencil/vitest render()/vi.*.
• Upgrade @stencil/core and introduce pnpm patch to mock ElementInternals.attachInternals() for spec tests.
