feat: implement progress indicators and status updates

- Enhanced dependency analyzer with AnalyzeActionFileWithProgress() method supporting optional progress callbacks
- Added progress bars to analyzeDependencies() and analyzeSecurityDeps() functions for batch operations
- Added IsQuiet() method to ColoredOutput for proper quiet mode handling
- Progress bars automatically show for multi-file operations (>1 file) and respect quiet mode
- Refactored analyzer code to reduce cyclomatic complexity from 14 to under 10
- Updated TODO.md to mark progress indicators task and all security tasks as completed
- All tests passing, 0 linting issues, maintains backward compatibility

Provides professional user experience with clear progress feedback for long-running operations.
