Release v0.4.1 - Smart dependency detection for CLI and GUI

Major features:
- Smart dependency detection scans directory file types
- Only prompts for dependencies actually needed
- CLI: Interactive prompts with progress reporting
- GUI: Modal dialog with Install/Skip/Cancel options
- Better UX for cargo install users on all platforms

Smart Detection:
- Scans up to 1000 files at max depth 3
- Detects image files → prompts for tesseract
- Detects video files → prompts for ffmpeg + tesseract
- Detects HEIC files → prompts for imagemagick (Windows/Linux)
- Separates required (exiftool) from optional dependencies

CLI Enhancements:
- Checks dependencies before processing directory
- Required deps missing → error and exit with install instructions
- Optional deps missing → interactive [Y/n] prompt
- Progress: ⏳ Installing... ✓ Done

GUI Enhancements:
- Modal dialog shows missing dependencies before analysis
- Lists required and optional deps separately
- Progress spinner during installation
- Three buttons: Install, Skip, Cancel
- Auto-proceeds to analysis after successful install

Technical Details:
- Extension-based file detection (fast, no metadata extraction)
- Thread-safe progress updates using Arc<Mutex<String>>
- Progress callback: Box<dyn Fn(&str, u8) + Send>
- DependencyNeeds struct separates required vs optional

Benefits:
- No false positives (only prompts for needed deps)
- Cargo install users get prompted on first run
- MSI installer users only prompted if auto-install failed
- Clear messaging about required vs optional deps
- Fast directory scanning with depth/file limits

Release v0.2.3 - Cross-platform binaries with Homebrew support
