fix: prevent auto-resume of old Codex sessions from before startup

CODEX_SESSION_SCANNER was incorrectly auto-resuming old sessions because
session files persist after Codex exits. Fixed by:

1. Only matching sessions created AFTER hapi startup (reject if
   sessionTimestamp < referenceTimestampMs)
2. Snapshot resumeSessionId at startup so scanner callbacks don't
   affect codexLocal's launch parameters
3. Updated session timestamp test to verify boundary conditions
