refactor(graceful): use slices.Backward

[colinaumaty]

Description

Use slices.Backward when invoking the graceful process stop stack. This expresses the required LIFO order directly and preserves panic recovery and timeout behavior.

How Has This Been Tested?

• Tested CCTX in localnet
• Tested in development environment
• Go unit tests
• Go integration tests
• Tested via GitHub Actions

---

Note

Low Risk
Behavior-preserving refactor in shutdown ordering only; no change to timeout, panic handling, or stop registration.

Overview
Shutdown stop-stack iteration now uses slices.Backward instead of a manual index loop, so LIFO teardown is expressed directly while keeping the same panic recovery, timeout, and logging around ShutdownNow.

Confidence Score: 5/5

The PR appears safe to merge.

Summary

The PR replaces the index-based reverse shutdown loop with slices.Backward.

• Shutdown callback order remains LIFO.
• Panic recovery and timeout handling remain unchanged.
