Subject: [PATCH] feat: add starship bash prompt support to base and nix images

Install starship cross-shell prompt with a minimal configuration
that shows directory, git branch/status, Node.js version, nix shell
indicator, command duration, and a colored prompt character.

- Base image: install via official install script, copy starship.toml,
  init in .bashrc
- Nix image: add starship package, writeTextDir config, init in .bashrc
- Devops image inherits from base automatically
