ci: fix the two downstream jobs (global-install npm pack, windows-integration open)

These jobs ran for the first time once the Windows matrix hang was fixed:

- Global Install: `npm pack` runs the `prepare` script (`husky`), but husky isn't
  installed in that job (no devDeps) → "husky: not found", exit 127. Guard it:
  `prepare: husky || true` (husky's recommended pattern for envs without devDeps;
  still installs hooks for local dev when husky is present).
- Windows Integration: `agent-browser open` defaults to auto-connect and looked
  for an existing Chrome on a debug port, which a fresh CI runner lacks → "Could
  not connect". A CI smoke test should spawn its own browser: use `--launch`.
