iii-directory

The directory worker is how an agent finds its way around the engine. It exposes five surfaces: function search (directory::search_functions), installed-worker docs (directory::skills::*), chat identity prompts (directory::system-prompts::*), reusable agent profiles (directory::agents::*), and the public worker catalogue (directory::registry::*). A download pulls a bundle onto disk, and each filesystem-backed family also takes direct create / update / delete calls — those are this worker's only writes. Everything else here is read-only.
