release.sh

#!/usr/bin/env bash
# release.sh — cut a new SpliceCraft release
#
# Usage:  ./release.sh 0.2.1
#
# Does:
#   1. Bumps the version in BOTH pyproject.toml and splicecraft.py
#   2. Runs the test suite (aborts on any failure)
#   3. Builds the package locally (aborts if twine check fails)
#   4. Commits the bump, tags v<version>, and pushes
#   5. GitHub Actions (publish.yml) then builds + uploads to PyPI
#
# Prereqs (one-time, see README):
#   - Trusted Publishing configured at pypi.org for this project
#   - git clean working tree (commit everything else first)
#
# The whole thing takes ~2 minutes from run to "live on PyPI".
