[vitest-pool-workers] Make workerd verbose logging configurable

[dmmulroy]

Adds a narrow, typed verbose option to cloudflareTest() / cloudflarePool() configuration and forwards it to the shared Miniflare options. This allows users to set verbose: false when caught Durable Object RPC errors would otherwise produce workerd structured INFO logs on stdout.

The option defaults to true, preserving existing behavior. This intentionally does not expose handleStructuredLogs or other arbitrary shared Miniflare handlers.

Validation:

• pnpm -w test:ci -F @cloudflare/vitest-pool-workers -- structured-logs.test.ts
• pnpm check --filter @cloudflare/vitest-pool-workers
• pnpm exec oxfmt --check packages/vitest-pool-workers/src/pool/config.ts packages/vitest-pool-workers/src/pool/index.ts packages/vitest-pool-workers/test/structured-logs.test.ts .changeset/quiet-taxis-listen.md

The full package suite was also run, but currently fails unchanged on main: the temporary test installation resolves Vitest 4.1.10, whose output format no longer matches existing assertions in console.test.ts, chunking.test.ts, and filtering.test.ts. Running console.test.ts against a stashed clean main reproduced the same three failures.

  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this repository's package README delegates the detailed configuration reference to cloudflare-docs; the public option includes inline typed documentation and a changeset.
