fix: use cross-env for Windows-compatible env variables and fix vitest electron path

Unix-style `VAR=value` syntax in npm scripts doesn't work on Windows.
Added cross-env to build:production, test, test:extension, and test:webview scripts.
Changed vitest.nodeExecutable to point to the actual electron binary instead of
the .bin shim, which doesn't resolve on Windows (only electron.cmd exists there).
