#!/usr/bin/env bash
# PowerLab — one-shot developer bootstrap
#
# Brings up the entire stack with a single command:
#   1. starts every backend service (./start.sh --build on first run)
#   2. installs UI dependencies if needed
#   3. starts the Vite dev server in the foreground
#
# Stops cleanly with Ctrl-C — both backend and UI are torn down.
#
# Usage:
#   ./dev.sh              first run, or after pulling new code (rebuilds binaries)
#   ./dev.sh --no-build   skip the backend rebuild (faster restarts)
#   ./dev.sh --stop       stop everything started by this script
