Subject: [PATCH 2/2] fix: prevent build failure when git is not installed but
 .git directory exists

Added ContinueOnError and exit code check to the SetGitCommitHash target
so the build gracefully skips embedding the git commit hash if the `git`
executable is unavailable, rather than failing the entire build.
