+ * Agent Banner — ASCII art at the top of the pi app on startup
+ *
+ * Displays the agent logo/banner above the editor when a session starts or when
+ * switching to a new session (/new). Hides automatically on first user input.
+ * Art is read from ~/Desktop/agent.txt, or falls back to embedded default.
+ * Footer is handled by footer.ts (model widget + status bar).
+ *
+ * Usage: Add to packages in settings.json
