0.1.5

CI: use npm install instead of npm ci, bump Node to 22

The strict lockfile match npm ci performs kept failing in CI even
after a clean local regen — local npm 22 and CI npm 20 resolved
electron-builder's transitive deps differently. Match local Node and
loosen install so the build is no longer gated on a perfectly-shaped
lockfile.

Bump to 0.1.5.
