# Usage:
#   ./publish.sh "commit message"     # run tests, commit, push
#   ./publish.sh "commit message" --skip-tests   # bypass test gate
#                                                  (use when flakes are known-flaky)
#   ./publish.sh --status             # show current working-tree state
#
# Runs Flutter + React unit tests before committing; aborts on failure
# unless --skip-tests is passed. E2E tests are NOT run here (they're
# slower and live in CI).
