CRITICAL findings:
P7-1: New() returns half-built Core on option failure (no error return)
P7-2: ServiceStartup fails → os.Exit(1) → no cleanup → resource leak
P7-3: ACTION handlers have NO panic recovery (PerformAsync does)
P7-4: Run() has no defer — panic skips ServiceShutdown
P7-5: os.Exit(1) bypasses ALL defers — even if we add them
Additional:
P7-6: Shutdown context timeout stops remaining service cleanup
P7-7: SafeGo exists but nobody uses it — the safety primitive is unwired
P7-8: No circuit breaker — broken handlers called forever
The error path through Core is: log and crash. No rollback, no cleanup,
no recovery. Every failure mode ends in resource leaks or silent state
corruption. The fix is: defer shutdown always, wrap handlers in recover,
stop calling os.Exit from inside Core.
