feat: add in-place editing and smart file detection

- Updated analyze command to support in-place editing with config
- Added smart file detection to analyze and convert commands
- Commands now detect extracted date files vs source files
- Respects postProcessOpenInNewFile and openResultsSideBySide config
- Aligns UX with numbers-le for consistency across all extensions
