feat: add Fyne GUI mode with interactive flashcard management

- Add --gui flag to launch interactive GUI mode
- Implement word navigation with prev/next buttons through existing cards
- Add delete functionality to remove unwanted flashcards
- Add fine-grained regeneration (image-only, audio-only, or both)
- Implement audio playback using mpg123 on Linux
- Auto-load first word on startup if cards exist
- Save translation files for navigation persistence
- Use DALL-E 2 with 512x512 images (half size)
- Update audio speed to 0.9 (from 0.8)
- Add comprehensive GUI documentation

+# GUI Mode for TotalRecall
+
+TotalRecall now includes an interactive GUI mode for a more user-friendly flashcard generation experience.
+
+## Prerequisites
+
+The GUI mode requires Fyne, which has the following system dependencies:
+
+### Linux
+```bash
+# Debian/Ubuntu
+sudo apt-get install gcc libgl1-mesa-dev xorg-dev
+
+# Fedora
+sudo dnf install gcc mesa-libGL-devel libXcursor-devel libXrandr-devel libXinerama-devel libXi-devel libXxf86vm-devel
+```
+
+### macOS
+No additional dependencies required (uses system frameworks).
+
+### Windows
+No additional dependencies required if using MinGW or similar.
+
+## Running GUI Mode
+
+```bash
+./totalrecall --gui
+```
+
+## Features
+
+The GUI provides:
+
+1. **Interactive Input**: Enter Bulgarian words one at a time
+2. **Live Preview**: See generated images and hear audio pronunciation
+3. **Fine-grained Regeneration**: 
+   - Regenerate just the image (cycles through different results)
+   - Regenerate just the audio (uses a different voice)
+   - Regenerate both
+4. **Session Management**: Keep track of all generated cards in a session
+5. **Export to Anki**: Export all saved cards to CSV format
+
+## GUI Layout
+
+- **Top Section**: Input field for Bulgarian words with submit button
+- **Middle Section**: 
+  - Image display with navigation (if multiple images)
+  - Audio player with play controls
+  - Translation display
+- **Bottom Section**: Action buttons
+  - "Keep & Continue" - saves the current card
+  - "Regenerate Image" - gets a new image
+  - "Regenerate Audio" - generates with a different voice
+  - "Regenerate All" - regenerates everything
+
+## Building from Source
+
+If you're building from source and encounter issues with the GUI:
+
+1. Ensure you have the system dependencies installed (see Prerequisites)
+2. The build might take longer the first time as it compiles Fyne
+3. If the build times out, try building without the GUI first:
+   ```bash
+   go build -tags nogui ./cmd/totalrecall
+   ```
+
+## Troubleshooting
+
+- **Build fails**: Check that you have the required system dependencies
+- **GUI doesn't start**: Ensure you're running in a graphical environment
+- **Audio doesn't play**: The current implementation shows audio controls but actual playback requires additional audio libraries
