- mark_played MCP action introduced
- Group read receipt logic using original sender JID

Bug Fixes
- Group read receipts fixed to use the original sender JID instead of the local device

Clients must adapt to the new `/newsletter/messages/{server_id}/download` endpoint and handle the updated poll vote webhook payload. No migration is required for the previous Kubernetes Agent Sandbox features as the project scope has shifted significantly.
