# Release EvoScientist to git.foksai.com.
#
# Usage:
#   scripts/release.sh 0.2.3 "Release notes text"   # bump pyproject, tag, publish
#   scripts/release.sh 0.2.2 "Release notes text"   # version == pyproject: reuse existing tag
#
# Requires: GITEA_TOKEN (write:repository), uv, shasum, jq, curl.
# Optional: GITEA_BASE_URL (default https://git.foksai.com), GITEA_REPO (default ouyangbo/EvoScientist).
#
# The wheel/sdist are built in a temporary git worktree at the tag so dirty
# working trees never leak into published artifacts.
