fix(deps): upgrade happy-dom to v20 + pin rollup/postcss CVEs (#20)

- Upgrade @happy-dom/global-registrator from ^15.11.0 to 20.9.0
- Pin rollup to 3.30.0 and postcss to 8.5.10 via overrides
- Add { url: 'http://localhost/' } to GlobalRegistrator.register()
  (required by happy-dom v20 API)
- Add .devcontainer/ to .gitignore
- Fix pre-existing biome lint issues in viewport/iris test files
  (import order, Number.parseInt)
