Reimplements the useful parts of #385 cleanly.
Adds two small cross-platform helpers under `openjarvis.core.utils`:
- `get_python_executable()` — prefers `python3`, falls back to `python` for Windows / minimal distros that only ship the unversioned name.
- `open_browser(url)` — `webbrowser.open` by default; on Windows uses `cmd /c start "" <url>` to avoid console-host edge cases.
Swapped at every hardcoded `python3` / `webbrowser.open` site: `connectors/oauth.py`, `evals/scorers/livecodebench.py`, `scripts/oauth_all.py`, `scripts/install/install.sh` (adds `PY_CMD` detection block), `scripts/quickstart.sh` (adds `MINGW*|MSYS*|CYGWIN*) cmd /c start` case), and the two affected test files. Test files wrap `get_python_executable()` in `shlex.quote()` before interpolating into `shell=True` strings — Windows interpreter paths often contain spaces.
Deliberately different from #385: `openjarvis.core.__init__` does NOT re-export `DEFAULT_CONFIG_DIR` (would have raised ImportError because it's in `openjarvis.core.config`, not the package `__init__`; re-exporting would also force eager import of the heavy config module at every `import openjarvis.core`). `oauth.py` keeps `from openjarvis.core.config import DEFAULT_CONFIG_DIR` alongside the new `from openjarvis.core import open_browser`.
Original API surface and call-site sweep by @sanjayravit in #385 — huge thanks for the careful Windows-compatibility audit. This PR preserves your design while fixing the ImportError edge cases caught during review.
