Greptile Summary

This PR bumps the aw-server git submodule from 153e7fd to aa848ce, pulling in one upstream commit that fixes a lock-timeout race condition where heartbeats were previously allowed to proceed unsafely instead of being rejected. The change is a single-line submodule pointer update with no modifications to any other file in this repository.

Confidence Score: 5/5

Safe to merge — single submodule pointer update pulling in a targeted safety fix with no side-effects in this repo.

The entire change is a one-line submodule bump. The included upstream commit is a defensive fix (reject on lock timeout), which improves correctness and safety. No other files in this repository are touched, and there are no logic, syntax, or security concerns introduced here.
