self-review 2026-07-28: close ISE lifecycle observability gaps

Browse Source 
- session_start now also posted to the HTTP Engram via ise_post: the
  local engram_node_full write never crossed to the observable stream
  (sync flows HTTP->soul only), so boots 5+ were invisible — last
  visible session_start was boot 4, two weeks ago
- graceful shutdown emits a final ISE with boot/pulse/uptime; a boot
  with no shutdown event now reliably signals a crash/SIGKILL
- empty /api/sync responses emit a sync_empty warn ISE instead of
  being silently skipped — unreachable engram no longer looks
  identical to quiet-but-healthy
- sync backflow prune reads ENGRAM_ISE_RETENTION_MS instead of
  duplicating the 48h magic number server.el already honors
