# bump-and-publish.sh — One-command version bump, build, publish, and cleanup.
#
# Usage:
#   ./scripts/bump-and-publish.sh patch          # 0.1.1 → 0.1.2
#   ./scripts/bump-and-publish.sh minor          # 0.1.1 → 0.2.0
#   ./scripts/bump-and-publish.sh major          # 0.1.1 → 1.0.0
#   ./scripts/bump-and-publish.sh 2.0.0          # set explicit version
#   ./scripts/bump-and-publish.sh patch --dry-run # everything except npm publish
#
# Steps:
#   1. Bump version (cli/package.json + cli/src/index.ts)
#   2. Build for npm (token check, typecheck, esbuild, publishable package.json)
#   3. Preview (npm pack --dry-run)
#   4. Publish to npm (unless --dry-run)
#   5. Restore dev package.json
#   6. Commit and tag
