test-version-bump.sh

#!/usr/bin/env bash
# Dry-run the version bump logic used by .github/workflows/bump-version.yml.
# Creates temporary copies of the version files, applies the same sed/awk
# transformations, and verifies all expected values are written correctly.
# Exits non-zero if any check fails.
#
# Usage:
#   ./scripts/test-version-bump.sh                  # default: 0.99.0 build 99
#   ./scripts/test-version-bump.sh 1.2.3 42         # custom version and build
