// Resolve electronDist at runtime (#38673, #47917): electron-builder 26.8.x can
// re-unpack a broken Electron.app; reusing the installed dist dodges that.
// npm workspace hoisting is non-deterministic — require.resolve finds electron
// wherever it landed. Dist present → -c.electronDist=<abs>/dist; absent → let
// electron-builder fetch via @electron/get (electronVersion + ELECTRON_MIRROR).
