Module session 

Persistent terminal sessions with scrollback and lifecycle management.

A Session wraps a Terminal and adds:

• a configurable ring-buffer of recent output (scrollback, default 256 KiB),
• client attach/detach tracking,
• orphan detection (no clients for 60 s → auto-remove).

SessionStore is the global session registry. Each session gets a reaper task that periodically checks for removal conditions.
