Migrate from Yarn to pnpm

- Replace Yarn 4.0.2 with pnpm 10.29.3 as the package manager
- Add pnpm-workspace.yaml and .npmrc configuration
- Update all scripts to use pnpm commands
- Rename getYarnWorkspaces() to getWorkspaces() in scripts/helpers.ts
- Update CI workflow to use pnpm/action-setup@v4 with Node 22
- Add @jitl/tsconfig as root devDependency for proper resolution
- Add variant packages as devDependencies for test resolution
- Fix TypeScript 5.9 compatibility in memory.ts (Int32Array<ArrayBuffer>)
- Upgrade typedoc to 0.28.17 for TypeScript 5.9 support
- Upgrade typedoc-plugin-markdown to 4.10.0
- Regenerate documentation with new typedoc version
