Subject: Fix GUI background image generation race conditions

- Add file.Sync() after image download to ensure data is flushed to disk
- Add double-checking in UI updates to prevent wrong card updates
- Fix background job completion to reload files when user navigates back
- Add file size validation in image display widget
- Improve error messages for image loading failures

This fixes two issues:
1. 'png: invalid format: not enough pixel data' error when navigating during generation
2. Images not updating when navigating back to a card after background generation completes

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-**totalrecall** - Bulgarian Anki Flashcard Generator
-
-A Go CLI tool that generates Anki flashcard materials from Bulgarian words:
-- Generates audio pronunciation using OpenAI TTS
-- Generates images using OpenAI DALL-E
-- Creates Anki-compatible output files
-
-## Important: Task Tracking
-**Always check TODO.md for the current implementation status and pending tasks.** The TODO.md file contains a comprehensive breakdown of all features and their completion status.
-
-## Build and Development Commands
-
-### Available Tasks (via Taskfile)
-```bash
-# Build the binary
-task
-# or
-task default
-
-# Run the application
-task run
-
-# Run tests
-task test
-
-# Install to Go bin directory
-task install
-```
-
-### Common Development Commands
-```bash
-# Build for current platform
-go build -o totalrecall ./cmd/totalrecall
-
-# Run without building
-go run ./cmd/totalrecall "ябълка"
-
-# Run tests with coverage
-go test -v -cover ./...
-
-# Check for race conditions
-go test -race ./...
-
-# Format code
-go fmt ./...
-
-# Lint code (requires golangci-lint)
-golangci-lint run
-```
-
-## Architecture Overview
-
-### Package Structure
-```
-totalrecall/
-├── cmd/totalrecall/          # CLI entry point
-├── internal/          # Private packages
-│   ├── audio/        # Audio generation (OpenAI TTS)
-│   ├── image/        # Image generation functionality
-│   ├── anki/         # Anki format generation
-│   ├── config/       # Configuration management
-│   └── version.go    # Version information
-```
-
-### Key Design Decisions
-1. **OpenAI TTS**: High-quality, natural-sounding Bulgarian pronunciation
-2. **Image generation**: Uses OpenAI DALL-E for AI-generated images
-3. **Configuration via YAML**: User-friendly configuration with viper
-4. **Cobra for CLI**: Industry-standard CLI framework
-
-### External Dependencies
-- **OpenAI API Key**: Required for both audio generation and image creation
-
-## Testing Approach
-1. Unit tests mock API calls
-2. Integration tests use real services when available
-3. Test with common Bulgarian words: ябълка, котка, куче, хляб
-
-## Common Issues and Solutions
-
-
-### Package Declaration Error
-If you see an error about `package main`, ensure `cmd/totalrecall/main.go` has:
-```go
-package main  // NOT package bulg
-```
-
-## Development Workflow
-1. Check TODO.md for next tasks
-2. Create feature branch
-3. Implement with tests
-4. Update documentation
-5. Run full test suite
-6. Submit for review
-
-## Bulgarian Language Notes
-- Input should be in Cyrillic script
-- Common test words: ябълка (apple), котка (cat), куче (dog)
-- OpenAI voices: nova, alloy, echo, shimmer (work well for Bulgarian)
