Orphaned vitest config references missing dependency

Low Severity

The vitest.config.mts file imports from @cloudflare/vitest-pool-workers/config, but neither @cloudflare/vitest-pool-workers nor vitest appear in the package.json devDependencies. Other cloudflare test apps (e.g. cloudflare-mcp, cloudflare-workers) also have this file but include the corresponding dependencies. No script in package.json references vitest either, making this file dead code with a broken import — likely copied from a template without adapting.
