[Client] Fix crash when local game commands are sent after shutdown (#7714)

* [Client] Fix crash when local game commands are sent after shutdown

* [Network] Fix formatting in local client debug log

* [CI] Keep the vcpkg submodule pointer on the manifest baseline

vcpkg.json asks for builtin-baseline 9eec002 (vcpkg 2026.10.16), but the
submodule gitlink was still at 9e593bb. The runners check submodules out
shallowly, so vcpkg-tool cannot read versions/baseline.json out of the baseline
commit and every vcpkg leg (Windows and all macOS) fails in CMake configure
with:

  failed to `git show` versions/baseline.json

git phrases that as "path ... exists on disk, but not in <sha>" even when the
commit is simply absent from the shallow clone, so it reads like a tooling or
network failure rather than a mismatched pointer. Point the submodule back at
9eec002, and add a cheap job that fails when the gitlink and builtin-baseline
disagree, before the five build legs pay for it.
