Pull request overview

This PR syncs dependency and tooling state from the dev branch into master, updating React-related devDependencies and refining the shared React ESLint configuration behavior (especially around JSDoc enforcement).

Changes:

• Update @joint/vitest-plugin-mock-svg devDependencies to React 19.1.1 and newer React type packages.
• Adjust @joint/eslint-config React flat-config to enforce JSDoc descriptions for public API (as warnings) while explicitly relaxing JSDoc rules for stories/tests, and broaden file globs to include stories/.
• Regenerate yarn.lock to reflect the dependency updates (including new React/scheduler entries).
