Uh oh!

Summary
- point missing-binary errors to the existing
scripts/download_binary.py helper
- replace the stale README anchor with the local-development documentation in
CONTRIBUTING.md
- add a regression assertion for both actionable references
Testing
uv run --frozen pytest tests/test_sea_binary.py -q (5 passed)uv run --frozen ruff check .uv run --frozen pyright -p .uv run --frozen mypy --platform linux .- full Python 3.9 and 3.14 suites run on Windows; only the pre-existing Windows failures addressed by Make byte fixtures checkout-stable and run tests on Windows CI #355 remained
Fixes #353
Summary by cubic
Corrects SEA missing-binary error guidance so local development instructions are accurate. Previously the error pointed to a non-existent script and a stale README anchor; it now references the correct helper script and CONTRIBUTING.md. No behavior change beyond error text.
- Error now suggests: "uv run python scripts/download_binary.py" (replaces "scripts/download-binary.py").
- Updates the help link to
https://github.com/browserbase/stagehand-python/blob/main/CONTRIBUTING.md.
- Adds a regression test asserting both the command and link in the error message.
Fixes #353.
Written for commit a25a20e. Summary will update on new commits.
