# devcontainer.sh — devcontainer helper for this repo
#
# Usage:
# ./devcontainer.sh <command>
#
# Commands:
# up build + start the devcontainer (idempotent)
# shell attach a bash shell; auto-ups if not running
# down stop the devcontainer
# rebuild remove + rebuild from scratch, no cache
#
# Examples:
# ./devcontainer.sh shell # one-shot: up if needed, then bash
# ./devcontainer.sh rebuild
