Module session 

Session management for multi-user support

Provides session groups, virtual terminal assignment, session isolation, and login/logout lifecycle management. Each session represents a user’s login context with its own process group, VT assignment, and state.

Sessions are identified by a SessionId (u64) and tracked by a global SessionManager protected by a spin mutex. A maximum of 8 concurrent sessions is enforced.
