Summary by cubic

Adds an owner-only Telegram /goal command to create and track Agency goals from chat. It saves the goal, opens a topic in groups, and starts the generator so cards appear in Telegram and the Mini App.

• New Features
  • Adds /goal <goal> command and help text; shows usage if missing; owner-only.
  • In groups, creates a new forum topic for the goal and records it in the Mini App (stores tg_chat_id/tg_thread_id).
  • Saves the goal to a private goals file (configurable via BUX_GOALS_FILE) and to miniapp.db (goals table).
  • Starts the Agency generator with a goal-aware prompt (reads goals file, avoids repeats, generates 10 high-signal cards); sends a success or fallback message.

^{Written for commit 4953b6f. Summary will update on new commits.}
