Devcontainers (and minimal / no-Ansible environments)

A file-only path that applies just the shell-framework subset on boxes that can't or won't run a provisioner — the dotfiles-lite use case, without a second repo. Background: the devcontainers blog post.

Items

• Add a file-only bootstrap for minimal / no-Ansible environments: an install.sh (plain shell, no Ansible/sudo/Python) that applies just the file-level subset (~/.profile.d/ aliases, starship config) — the lite path for servers, remote shells, and devcontainers/Codespaces (via their dotfiles hook). Covers the dotfiles-lite use case (a stripped-down subset for boxes that don't need the full toolchain) without a second repo
• Render the container/ payload from the same role templates and vars that generate ~/.profile.d/ on the host, so host and container share one source of truth
• No devcontainers role: Docker comes from the docker role, the spec lives per project, and the devcontainer CLI belongs in the node role's npm globals
