Refresh the npm dependency graph to remove 23 currently reported vulnerable packages, including the Critical Vitest issue. Keep the Vite 7 and Vitest 4 application tooling, use the patched ESLint 9 line with its matching config package, and preserve application code and the existing supported Node versions.
