#
# - creates a new remote using the fork's clone URL
# - creates a local branch tracking the remote branch
# - creates a new worktree in a parent folder, suffixed with "-pr-$PR"

# sample usage:
#   ./scripts/pr2wt.sh 12345
#   ./scripts/pr2wt.sh 12345 opencode
#   ./scripts/pr2wt.sh 12345 "cmake -B build && cmake --build build"
