#!/usr/bin/env bash
# install.sh: set up the kiban foundation on this machine.
#
# gstack-style: a plain git clone to ~/.konjo/kiban, no plugin marketplace. Idempotent
# and safe to re-run. Ledger state lives in ~/.konjo/state, outside the clone, so an
# update never touches it.
#
# What it does:
#   - clone konjoai/kiban into ~/.konjo/kiban if absent; otherwise run the self-update.
#   - create ~/.konjo/state if absent (never overwrite it).
#   - print (does not auto-edit your rc) the line to add bin/ to PATH.
