- Move renderer files to src/renderer/src/ (electron-vite standard)
- Move index.html to src/renderer/
- Remove root: '.' config that broke HMR
- Use ELECTRON_RENDERER_URL instead of VITE_DEV_SERVER_URL
- Update tsconfig paths for new structure
This fixes hot module replacement not working after the monorepo
restructure. The previous non-standard directory layout with root: '.'
caused electron-vite's HMR to fail silently.
