Note

Migrates launcher to async/await with no Bluebird, introduces dual CJS/ESM outputs, and updates server modes/tests and platform helpers accordingly.

• Launcher (core refactor):
  • Move from Bluebird to native async/await Promises across lib/detect.ts, darwin, linux, windows.
  • Refactor lib/utils.ts: export spawnWithArch and getOutput (no utils wrapper); replace utils.execa with direct execa.
  • Update platform helpers: async detect, parsePlist, mdfind, version resolution and timeouts (Linux snap detection, getVersionString).
  • Internal dedupe now via uniqBy with name-version key in lib/detect.ts.
  • Entry/module structure: add lib/index.ts; remove root index.ts; switch package to dual build outputs (cjs/, esm/), set main, module, types.
  • Tooling: add tsconfig.cjs.json, tsconfig.esm.json; update tsconfig.json (strict, declarations); ignore cjs/ & esm/; remove bluebird dep.
• Server (integration updates):
  • Convert startInMode paths for version, info, smokeTest, returnPkg, exitWithCode, run to async/await; inline pkg/info/exit logic (remove modes/pkg.ts, modes/exit.ts).
  • lib/modes/info.ts: export info async function; update usage in tests.
  • browsers/utils.ts: make ensureAndGetByNameOrPath async; handle launcher.detectByPath with try/catch.
• Tests and snapshots:
  • System test browser_path_spec.js migrated to async/await; disable video in run; update snapshot (no video section, Video: false).
