Claude QoL - Export, Fork, Search, and more

Adds several QoL tweaks and additional features to Claude.ai. This includes: - Text search across all chats - Chat Forking + Compacting - Search in chat - Advanced chat navigation - Advanced editing (Add files to past messages) - Text to speech (Via Elevenlabs/OAI/Browser) - TTS with character-based voices - Speech to text (Via Groq/OAI/Browser) - Preferences switcher - Per-chat style overrides - Chat exporting/importing to HTML/ZIP/Markdown/JSON Some of the above features require some form of external API service. The entire extension is built around a Bring Your Own Key principle - that is, you will have to provide your own API key. The source code is here: https://github.com/lugia19/Claude-QoL
