Release v0.2.0

Added

• Long message auto-splitting: responses are split at paragraph/line boundaries (4000-char limit) and sent as multiple messages instead of being truncated
• Typing keepalive loop: background task sends typing indicator at regular intervals during long tool calls to prevent Telegram from dropping the typing status

Fixed

• Removed 4000-character hard truncation from _clean_response; full response content is now preserved
• Inline option keyboard now only appears for AskUserQuestion degraded responses (via force_options flag), preventing false positives on numbered lists in regular replies
