# update.sh - Update astrbot-git AUR package
#
# This script handles the full update workflow:
#   1. Pull latest from origin (AUR)
#   2. Download and compute new pkgver from upstream repos
#   3. Bump pkgrel (always, to force rebuild even on hotfix changes)
#   4. Commit and push to both AUR and GitHub mirror
