Adds a `devtron: true` config option to @electron-forge/plugin-webpack and @electron-forge/plugin-vite that installs the @electron/devtron DevTools extension into the app during `electron-forge start`. The bootstrap is prepended as a raw banner to the compiled main process bundle in development only (webpack BannerPlugin / Rollup output.banner), so the bundler never parses it and `@electron/devtron` resolves from the app's node_modules at runtime. The snippet guards against packaged apps, non-main Electron processes, and ESM output without `require`. A shared helper in @electron-forge/core-utils validates that @electron/devtron is installed in the app (actionable error otherwise) and that the app's Electron version is >= 36 (warn and skip otherwise).
