fix(deps): Resolve Dependabot alerts

[MathurAditya724]

Refreshes the Action Toolkit, build tooling, and both dependency lockfiles so the root Action and standalone website resolve the patched releases for the open Dependabot advisories. The Toolkit upgrade removes the affected runtime undici, Octokit, and glob dependency chains; the website remains on compatible Vite 7 while moving React Router to its patched release.

The generated Action bundle is rebuilt. The configuration-loader test now uses an ESM-safe @actions/core mock required by the upgraded toolkit, and the Vitest coverage provider is aligned with the runner.
