# Multi-stage Dockerfile for the IronClaw agent (cloud deployment).
#
# Uses cargo-chef for dependency caching — only rebuilds deps when
# Cargo.toml/Cargo.lock change, not on every source edit.
#
# Build:
#   docker build --platform linux/amd64 -t ironclaw:latest .
#
# Run:
#   docker run --env-file .env -p 3000:3000 ironclaw:latest
