Description of changes

• Add shared test-only utilities for resolving v0 settings and v1 token layers into stable color-only snapshots.
• Add platform-resolved macOS and Win32 pinning themes.
• Teach the React and React Native Jest presets to discover .test.macos.ts and .test.win32.ts files.
• Add paired macOS and Win32 token snapshots for 22 stable and experimental component packages.
• Refresh the previously undiscovered StackUtils.test.win32.ts expectations to the current numeric spacing contract.
• Add package-local test dependencies, TypeScript project references, Jest configuration, and a patch changeset where required.

Verification

• yarn build — passed.
• yarn format:check — passed.
• yarn lage lint — passed.
• yarn lage test — passed; 4 tasks executed and 77 package tasks reused valid cached results.
• yarn test in packages/components/Stack — passed: 14 Win32 tests, 2 macOS tests, and 5 snapshots.
• Focused package snapshot suites — passed for all 44 platform test files and matching snapshot files.
• yarn lint-lockfile and dependency alignment/constraint checks — passed.

Before	After
Component color tokens were not comprehensively pinned for macOS and Win32, and .test.<platform>.ts files were not discovered by the Jest presets.	v0 and v1 color token trees are pinned in platform-specific snapshots across 22 packages, and the Jest presets execute the correct macOS and Win32 modules.
