fix(ci): use npm install instead of npm ci

npm ci fails on CI (Node 22.x / npm 10) due to magicast deduplication
conflict in better-auth's dependency tree. c12@3.1.0 requires
magicast@^0.3.5 but npm hoists magicast@0.5.2. npm 10 is stricter
about this than npm 11. Using npm install until upstream resolves the
dependency conflict.
