The renderer opens with sandbox:true, and Electron sandboxed preload scripts
only support CommonJS. The preload was emitted as ESM (package.json is
"type": "module"), so it failed to load silently and window.dshApp was never
injected. The About section then fell back to plain-web mode: current version
stayed on the '—' fallback and check-for-updates reported up-to-date without
querying. Build the preload with esbuild into lib/types/preload.cjs and point
the main process at it.
