Subject: [PATCH] fix: improve yarn cache strategy to prevent immutable
 lockfile errors

- Cache .yarn/cache instead of node_modules to avoid inconsistencies
- Include both yarn.lock and package.json in cache key hash
- Update restore-keys to be more specific with package.json hash
- This prevents CI from using stale caches after dependency updates
