New: Claude acceleration beta

Claude now has an experimental render-windowing path similar to ChatGPT.

LeanThreads can detect Claude conversation-read responses, capture the full visible conversation snapshot for the drawer/export tools, and return a trimmed recent-message window to the Claude page so long Claude chats can render more lightly.

Full ChatGPT support:
- configurable active-message render window
- local older-context drawer
- Markdown / JSON export
- summary prompt export
- diagnostics export
- tab-local context handling
- desktop + Android unified manifest
- mobile icon launcher

Additional AI providers now have export/context capture only:
Claude
Gemini
Microsoft Copilot
Perplexity
Mistral Le Chat
DeepSeek Chat
Poe

Recent fixes:

• Removed ChatGPT citation junk from exports.
• Fixed tab switching so each tab has its own context.
• Added provider diagnostics export.
• Tuned capture for Gemini, Copilot, Perplexity, Mistral, DeepSeek, and Poe.
• Fixed Claude assistant response capture.
• Fixed DeepSeek duplicate paragraph export.
• Fixed Poe role inversion.
• Added Android/mobile icon-only launcher.
