Smart auto-compact — skip if session is ending

Problem Statement

Auto-compact triggers based on context fill, regardless of whether the session is still active. If the user is
wrapping up (e.g., running session-close commands, idle, or context hasn't grown in N messages), compacting wastes tokens and adds latency for a summary no one will read.

Proposed Solution

Before auto-compacting, check for session-end signals (idle time, recent message velocity,
explicit /stop or hook trigger). If the session appears to be closing, skip compact or defer it.
