install.sh

#!/usr/bin/env bash
# Dotfiles installer — cross-platform entry point
#
# Called automatically by GitHub Codespaces, DevPod, and VS Code Dev Containers
# when this repo is configured as a dotfiles repository.
#
# Scenarios:
#   macOS (native)     → delegates to just all / make all (full setup)
#   Container/Linux    → installs stow, links CLI configs only (~5 seconds)
#
# Preferred usage:
#   just all          (if just is installed)
#   make all          (universal fallback)
#   ./install.sh      (backwards compatibility + container auto-detection)
#
# First-time macOS setup from scratch:
#   curl -fsSL https://raw.githubusercontent.com/snics/dotfiles/master/bootstrap.sh | bash
