name: Windows Setup E2E

# End-to-end fresh-install gate for Windows. Runs `./setup` on a clean
# windows-latest checkout and asserts the build completes, binaries
# resolve via find-browse, and the gstack-paths state root resolves
# cleanly. Catches Bun shell-parser regressions in package.json's build
# chain (#1538, #1537, #1530, #1457, #1561) before they reach users.
#
# Separate from windows-free-tests.yml because that one runs a curated
# unit-test subset; this one exercises the install path itself.
#
# Runner: GitHub-hosted free windows-latest. ~3-5 min total.
