# Git post-push hook: Automatically publish dev versions after push
# Installs as .git/hooks/post-push in package directories
#
# Behavior:
# - Runs after successful git push
# - Auto-publishes dev version to registry
# - Non-blocking (runs in background)
# - Respects package metadata (_.publish, [tool.lilith].publish)
# - Only runs for publishable packages
