/**
 * BOB Chat — Sovereign Logic Machine
 *
 * BOB produces words from: QRNG → HolyC NIL → Dictionary → Prolog → Ada → WORM
 * No LLM required. No Ollama required. BOB is self-contained.
 *
 * The right panel (Groq/GPT-4o/Gemini) is optional comparison only.
 * Run --solo to get pure BOB with no external connections at all.
 *
 * Usage:
 *   node autonomous/chat.mjs               BOB only — zero external calls (DEFAULT)
 *   node autonomous/chat.mjs --verbose     BOB only + show internal routing
 *   node autonomous/chat.mjs groq          BOB + Groq comparison side panel
 *   node autonomous/chat.mjs gpt4o         BOB + GPT-4o side panel
 *   node autonomous/chat.mjs gemini        BOB + Gemini side panel
 *   node autonomous/chat.mjs --compare     BOB + Groq (explicit compare flag)
 *
 * Commands inside chat:
 *   /worm              show sealed WORM history
 *   /agent             run a live autonomous tick
 *   /3d [shape]        render 3D ASCII (torus cube sphere pyramid bob)
 *   /3d torus --anim   animated rotation
 *   /img [path]        convert image to ASCII
 *   /quit              exit
