Rebased onto current main, where the electron test harness migrated from
node:test to vitest (test:desktop:platforms = `vitest run --project electron`,
auto-discovering electron/*.test.ts). Swap the node:test import for vitest and
drop the .ts-extension import hack; the obsolete package.json node --test list
edit is dropped in the cherry-pick resolution since vitest auto-discovers.
