ci: pin unit-test Electron to 42.3.0 (electron@latest 42.3.2 breaks oxc transform on macOS)

The unit-test script runs npx electron@latest. Electron 42.3.2 (2026-06-02) breaks the oxc transform under Electron-as-node on macOS arm64, failing the macOS unit job ("Expected } but found EOF") regardless of repo deps. Pin to 42.3.0 (last green) so CI no longer floats with Electron releases. Also carries the windows-2025-vs2026 runner rename.
