# Creates one worktree per issue, each on its own issue-named branch. main is left untouched
# and reserved as the integration point. Run from inside your tasks-app repo.
#
# This is Module 7's `git worktree add` repeated with a naming convention. The convention is the
# point: branch name carries the issue number, folder name mirrors the branch.
