Add determinism tests for verdict artifact generation and update SHA256 sums script
- Implemented comprehensive tests for verdict artifact generation to ensure deterministic outputs across various scenarios, including identical inputs, parallel execution, and change ordering. - Created helper methods for generating sample verdict inputs and computing canonical hashes. - Added tests to validate the stability of canonical hashes, proof spine ordering, and summary statistics. - Introduced a new PowerShell script to update SHA256 sums for files, ensuring accurate hash generation and file integrity checks.
