When an agent CLI exits without creating a session, we now log:
- Number of prior sessions and total session log bytes
- Child process exit status (exit code or signal)
- Explicit SESSION NONE warning with context
This will help diagnose whether the fatal runtime error
(output.write assertion) correlates with accumulated sessions,
budget exhaustion, or something else.
