closes #1684

Refs #2716. Follow-up to #2713.

Summary

  • pass Nitro's configured workflow.dirs through to both Vercel and local Workflow builders
  • keep the existing ['.'] fallback for Nitro integrations that do not configure workflow.dirs
  • cover the behavior in the Nitro builder tests

Verification

  • PATH="/tmp/workflow-pnpm10-bin:/Users/nathancolosimo/.cache/codex-runtimes/codex-primary-runtime/dependencies/node/bin:$PATH" pnpm vitest run packages/nitro/src/index.test.ts

Note: the first commit attempt hit the local Husky pre-commit install step because it invoked pnpm 11, which rejects this repo's current pnpm config layout. I reran the commit with HUSKY=0 after the focused Nitro test passed.
