Builds run in a fresh temporary module folder that is not a git repo, so Go embeds no vcs.revision/vcs.time settings in the binary. Plugins that read their version via debug.ReadBuildInfo() then have no data. Tailscale, for example, reports "<Tailscale version>-ERR-BuildInfo" in the Tailscale console. Initialize a git repo with one commit in the temp folder before compiling so Go can stamp valid VCS info. If git is missing or fails, a warning is logged and the build proceeds.
