feat: add message chunking in Telegram Send method

Browse Source 
Split HTML content into 4000-char chunks before sending to handle cases
where markdown-to-HTML conversion causes messages to exceed Telegram's
4096-character limit. Uses the existing SplitMessage utility which
preserves code block integrity across chunk boundaries.
