Enable users to study/work together in shared sessions with social features.

• /sessions - See all active sessions in the server
• Live session dashboard showing who's studying together
• Group leaderboards for collaborative time

Implementation Notes

• Need to handle session merging/splitting
• Should group sessions count time differently?
• Consider privacy settings (public vs private sessions)
• May need new Firestore structure for group sessions
• Should integrate with voice channel features

Voice Channel Integration

• Users in same VC could automatically form a group session
• Show VC members in session embed
• Track "study together" time as a separate stat

User Story

As a user, I want to study together with my friends and see who's actively working, so we can motivate each other and stay accountable.
