Smart archive and inbox cleanup

Use 'organize_conversation' with action 'archive' to archive a conversation with auto-return. Unlike LinkedIn's native archive, the conversation automatically comes back to your inbox when the other person sends a new message.

For bulk cleanup, use 'bulk_archive' to archive all stale conversations older than a set number of days (default 30). Only archives threads where you sent the last message and got no reply. Use dry_run=true to preview what would be archived.

All archived conversations are excluded from 'get_inbox_status' and 'list_conversations' by default.
