The rc.d drops privilege via su -m, which preserves the environment from
/etc/rc (HOME=/). Without an explicit ZOT_HOME, zot resolves to
/.local/state/zot — missing any AGENTS.md installed by the seed importer.
Pin ZOT_HOME to /var/db/colibri/.local/state/zot. The seed importer
(clawdie-iso) targets this same path, so AGENTS.md placed on the seed
reaches the autospawned zot's global slot.
