fix: improve neo-tree multi-selection detection and clean up logging

- Remove redundant vim.notify call from ClaudeCodeTreeAdd
- Enhance neo-tree multi-selection detection with multiple fallback methods
- Add comprehensive debug logging to identify which selection method works
- Try get_selection(), is_selected nodes, and state.selected_nodes approaches
- Better error handling and debugging for neo-tree integration
