# Rho — Universal installer
#
# Two modes, auto-detected:
#
#   User install (curl | bash, or run standalone):
#     curl -fsSL https://rhobot.dev/install | bash
#     Installs rho via npm. No repo clone needed.
#
#   Developer install (run from a git checkout):
#     git clone https://github.com/mikeyobrien/rho.git
#     cd rho && ./install.sh
#     Symlinks rho CLI from local source, installs local deps.
#
# Both paths end with: rho init + rho sync.
#
# Usage: ./install.sh [--force]
#   --force: overwrite existing config files
#
# Idempotent: safe to run multiple times.
