Run builds, tests, and other tooling inside a reproducible, containerized dev environment via the `ilo` CLI instead of on the host. Use this whenever a project relies on ilo, devcontainers, or container-based build environments — it has a `.ilo.rc` / `.ilo/ilo.rc`, `dev/` argument files, a `Containerfile`/`Dockerfile`, a `devcontainer.json`, a `devfile.yaml`, or a compose file — or when a command needs a toolchain the host is missing (no local JDK, Node, Go, Rust, Maven, etc.) and the work should happen in a container dev environment. Includes ready-to-use dependency-cache recipes for many languages and build tools, and how to keep files written in the container owned by you on the host (the `--remote-user` flag) when an image runs as root.
