Migrate to Yarn v6 (rc.15) via Yarn Switch

- Switch packageManager from yarn@4.13.0 to yarn@6.0.0-rc.15
- Change nodeLinker from pnpm to node-modules (PnP not ready for this repo)
- Remove yarnPath (Yarn Switch manages the binary instead)
- Remove preinstall script (node not in PATH in Yarn v6 subprocesses)
- Add @typescript/native-preview: latest to devDependencies
- Add resolutions for packages with invalid ^0.x semver
- Add .mise.toml for managing node and yarn versions
- Update getCatalog.ts to handle yarn config failures gracefully
- Regenerate yarn.lock with Yarn v6
