/**
 * [WHO]: Provides ChatRendererController + ChatRendererContext — transcript rendering:
 *        message→component mapping (addMessageToChat), session-context replay
 *        (renderSessionContext), initial transcript + welcome banner (renderInitialMessages),
 *        chat rebuild with optimistic-user dedupe (rebuildChatFromMessages), getUserMessageText
 * [FROM]: Depends on injected host capability closures + @catui/tui + message components + startup-wordmark;
 *         no InteractiveMode reference. Internal cross-calls go through ctx callbacks so
 *         host-side method patching (partial-mode tests) keeps intercepting them.
 * [TO]: Consumed by modes/interactive/interactive-mode.ts (held lazily as `this.chatRenderer`
 *       behind thin delegators: addMessageToChat / renderInitialMessages / rebuildChatFromMessages /
 *       getUserMessageText)
 * [HERE]: modes/interactive/controllers/chat-renderer.ts — P7 C-3c (extracted from
 *         InteractiveMode message-rendering block; behavior-preserving move)
