Fixes#58409 - Heartbeat system causes silent session reset leading to user data loss.
The issue occurred when automated system events (heartbeat, cron-event, exec-event)
triggered the session initialization logic, which evaluated session freshness based on
idle/daily reset policies. Stale sessions were reset, causing complete context loss.
Changes:
- Detect system event providers (heartbeat, cron-event, exec-event) in initSessionState
- Force freshEntry=true for system events to skip reset policy evaluation
- Add comprehensive test coverage for heartbeat no-reset behavior
This ensures automated check-ins preserve session continuity and never cause
accidental data loss.
