# Install or refresh the daemonless porting toolkit into an image repo.

# Usage:
#   /path/to/porting-toolkit/install.sh           # first install
#   /path/to/porting-toolkit/install.sh --refresh  # update existing
#
# Run from the image repo root. Copies .claude/, templates/, and scripts/.
# The cookbook is copied (not symlinked) so it works offline. After a port,
# PR new cookbook entries back to the toolkit repo.
