[Copilot]

Pull request overview

Refactors cyclonedx.contrib.bom.utils to simplify a few internal implementation details while keeping the public utilities (BomRefDiscriminator, BomDependencyGraphFlatMerger) functionally equivalent.

Changes:

• Reformatted __all__ into a multi-line list for readability.
• Simplified BomRefDiscriminator.from_bom() by replacing map(lambda ...) with generator expressions.
• Simplified a local variable initialization in _flatten_merge() (seen).
