# build.sh - Linux/macOS Build Script
#
# This script automates the process of building and running the Docker container
# with version information dynamically injected at build time.

# Hidden feature: Preserve usage statistics across rebuilds
# Usage: ./docker-build.sh --with-usage
# First run prompts for management API key, saved to temp/stats/.api_secret
