 * Set the version across all publishable packages and plugins in the monorepo,
 * then create a git commit and tag.
 *
 * Usage:
 *   bun run set-version 0.1.1          # stable release → npm "latest" tag
 *   bun run set-version 0.1.1-alpha.1  # pre-release  → npm "alpha" tag
 *   bun run set-version 0.1.1 --no-tag # bump only (no commit or tag)
 *   bun run set-version 0.1.1 --skip-changelog-check # emergency stable release
 *
 * All packages and plugins share a single version number (fixed versioning).
 * Pre-release suffixes (-alpha, -beta, -rc, etc.) are detected by the
 * publish workflow and published to the corresponding npm dist-tag.
