5.1: File upstream PR to PathOfBuildingCommunity/PathOfBuilding-SimpleGraphic

[braggpd]

Once macOS builds are stable (Phase 1–2 complete), open a PR to the upstream SimpleGraphic repo with the macOS system layer changes. Getting merged upstream is the only truly sustainable path.

• Rebase macos-port branch cleanly onto upstream master
• Open draft PR upstream, reference this issue tracker in the description
• Engage with maintainers (localidentity / wires77 on Discord)
