Tracking follow-up improvements and explorations after successfully upgrading Electron from v25 to v40 #3382

• Replace net.request() with net.fetch()
  • Modern API available since Electron 28
  • Location: src/main/net/request/metal-request.ts
• Replace req.abort() with req.destroy()
  • Location: src/main/net/request/metal-request.ts:142
• Migrate main process from CJS to ESM
  • Electron 28+ supports ESM. Already has "type": "module" in package.json and a TODO in esbuild.config.mjs:28.
  • Would change from "cjs" to "esm" format and output extension from .bundle.cjs to .bundle.js.
  • Currently deferred/not worth doing right now.
• Evaluate replacing @goosewobbler/electron-redux
  • The library is abandoned but Electron APIs are stable through v40. No urgency.
  • Upstream klarna/electron-redux v2.0.0 is the same code with worse packaging. @zubridge/electron is an actively maintained alternative if migration is desired.
