Enhanced LLM-first architecture with smart attachment handling

- Replaced complex if/else routing with LLM-driven SmartRouter
- Added LLM-first nodes for web search, data analysis, calculator
- Enhanced web search to fetch full page content instead of snippets
- Fixed attachment handling to only download when file_name exists
- Upgraded to GPT-4o for better reasoning
- Added comprehensive debug logging for attachment flow

-           - Don't use abbreviations for cities/names
-           - Write digits in plain text (e.g., "two" instead of "2")
