Code Review

This pull request correctly addresses the security vulnerability GHSA-xpqw-6gx7-v673 by updating the svgo dependency to version 3.3.3 using a pnpm override. The changes in pnpm-lock.yaml are consistent with this update. I've added a comment to correct a typo in the CVE number within pnpm-workspace.yaml. Please note that the same typo (CVE-2026-29074 instead of CVE-2024-29074) is present in the pull request title and description, which you may also want to correct for clarity and accurate tracking.
