refactor: save theme ID instead of entire theme object in config

unhappychoice · claude · unhappychoice · commit d475f01be66a · 2025-09-21T12:47:51.000+09:00
- changed ThemeConfig to store current_theme_id (String) instead of full Theme - ThemeManager now loads theme by ID from available themes at runtime - reduces config file size and improves maintainability - updated related tests and removed unnecessary ThemeManager methods - simplified theme management while maintaining functionality 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
