Pull Request Overview

This PR enhances error handling in the pre-compute stage by collecting and returning all encountered errors instead of failing on the first error. This allows for more comprehensive error reporting and better debugging capabilities.

Key changes:

• Modified read_args() to return both PreComputeArgs and a vector of errors instead of a single Result
• Updated error collection to continue processing after encountering errors in dataset and input file handling
• Enhanced PreComputeInputFileDownloadFailed error to include the file index
