* fix(electron): restore packaged desktop app loading
Rebuild and verify Electron native modules before packaging and use the Vite base URL for packaged asset preloads.
* test(preload-utils): cover non-root base urls
Adds broad coverage across stores, hooks, and runtime utilities while switching `vitest.config.ts` to an explicit whole-repo include list. This turns the coverage report into a real repo-wide baseline instead of an imported-file subset.
