This pull request introduces an optional projectRoot configuration to the builder setup, allowing explicit resolution of workflow module specifiers instead of relying on process.cwd(). The change is threaded through module discovery, SWC transforms, and the Next.js deferred builder, while maintaining backward compatibility when the option is not provided.

Configuration and resolution improvements:

  • Added an optional projectRoot property to the builder config, enabling explicit module resolution and reducing reliance on process.cwd().
  • Updated module discovery, SWC transforms, and the Next.js deferred builder to utilize the new projectRoot option, while preserving existing behavior if it is omitted.

  • Wall Time: Total testbench time (trigger workflow + poll for result)
  • Overhead: Testbench overhead (Wall Time - Workflow Time)
  • Samples: Number of benchmark iterations run
  • vs Fastest: How much slower compared to the fastest configuration for this benchmark
