PR Summary

Low Risk
Single dependency version bump in package-lock.json with no code changes; net effect is improved XSS sanitization behavior from upstream DOMPurify releases.

Overview
Updates the lockfile so the resolved dompurify package moves from 3.4.2 to 3.4.10 (integrity hash and tarball URL only). There are no application or config source changes in this PR.

That bump pulls in upstream sanitizer fixes and hardening from 3.4.3–3.4.10 (including security-related releases such as the 3.4.5 bypass fix, IN_PLACE / DOM clobbering and Shadow DOM improvements, and Trusted Types handling). dompurify appears in the tree as a dependency of mermaid, not as a direct app import change.
