Module engine 

Engine — shared business logic for both TUI and headless modes.

The engine owns the runtime, session, extensions, and event bus. Renderers (chatui TUI, headless chat) call into the engine for all non-visual operations.

Modules

commands

Engine-level command results — TUI-agnostic outcomes of slash commands.

session

Engine-level session management — save, load, resume, clear.

setup

Engine setup — boot sequence shared by TUI and headless modes.

stream

Engine-level stream processing — TUI-agnostic event handling.
