/**
 * Read-only report and easter-egg commands extracted from interactive-mode.
 *
 * These build informational output (usage/cost summary, changelog, hotkeys
 * table, render debug dump) or render an easter-egg component, appending to the
 * chat container and requesting a render. None mutate agent/session state, so
 * they operate through narrow `host` seams (chat container, TUI, and a few
 * read accessors) while interactive-mode keeps thin delegating wrappers.
