Bump dompurify to 3.4.0 in lockfile

This change updates @preact/signals-core but does not actually upgrade dompurify; the lockfile still resolves dompurify@3.3.3 in both packages and snapshots, so the intended security upgrade is not applied. As a result, merging this commit would leave the known vulnerable version in production while appearing to have fixed it.

Useful? React with 👍 / 👎.
