PackageBuildInfo (vendored)

Fork of DimaRU/PackageBuildInfo that replaces the upstream binary helper with a Swift executable.

The helper runs git with stderr discarded (FileHandle.nullDevice). That prevents messages such as fsmonitor_ipc__send_query: unspecified error on '.git/fsmonitor--daemon.ipc' from being mixed into stdout and spliced into generated packageBuildInfo.swift, which previously produced invalid Swift and Xcode parse errors.

Regenerate build info by building any target that applies PackageBuildInfoPlugin (e.g. PVUIBase).
