chore: clean up root folder by relocating config files (#448)

* chore: clean up root folder by moving config files

- Move renovate.json to .github/renovate.json
- Move electron-builder.yml to electron/electron-builder.yml
- Move electron.d.ts to electron/electron.d.ts
- Delete proxy.ts (unused dead code)
- Update package.json dist scripts with --config flag
- Use tsconfig.json files array for electron.d.ts (bypasses exclude)

Reduces git-tracked root files from 23 to 19.

* chore: regenerate package-lock.json to fix CI

* fix: regenerate package-lock.json with cross-platform deps

electron/electron-builder.yml
