navidrome/scripts/setup-worktree.sh

#!/usr/bin/env bash
#
# Setup a git worktree for Navidrome development.
# This script is called automatically by `make worktree` and by Claude Code's
# worktree isolation, but can also be run standalone:
#
#   ./scripts/setup-worktree.sh <worktree-path> [--go-only]
#
# Options:
#   --go-only   Skip frontend (npm) setup. Useful for agents working only on Go code.
