Pull Request Overview

This PR refactors the codebase to use a unified ParsedCommandLine struct in place of separate compiler options, root file lists, and diagnostics across compiler creation and test harness logic.

• Pass a single ParsedCommandLine config object into NewProgram and related functions.
• Update ProgramOptions and remove NewProgramFromParsedCommandLine.
• Adjust test utilities and runner components to construct or forward the new config type.

• [nitpick] The variable name opts here shadows the earlier opts used for core.CompilerOptions and mixes distinct types. Consider renaming this to progOpts or similar for clarity.

opts := ProgramOptions{

• [nitpick] This commented-out call looks outdated after replacing program initialization; consider removing the stale // updateProgram() comment.
