feat: add dynamic file structure context in AI chat

- Improved file structure formatting with tree-like visualization
- Added filtering for ignored files and folders
- Added scripts section to template context
- Fixed folder hierarchy display with proper indentation
- Maintains sorting with folders first, then files alphabetically
- Now uses actual project files instead of template structure
