feat: migrate to TypeScript 6 and add tsgo (#114)

* feat: migrate to TypeScript 6 and add tsgo

- Upgrade typescript from ^5 to ^6 across all packages
- Address TS6 breaking changes in tsconfig files:
  - Add explicit types array (new default is [])
  - Remove deprecated baseUrl (paths work without it)
  - Remove redundant esModuleInterop: true
  - Merge DOM.Iterable into DOM lib
- Install @typescript/native-preview for tsgo CLI
- Enable tsgo in VS Code settings
