Pull Request Overview

This PR refactors a variety of conditional constructs by replacing multiple if/else statements with switch statements to improve code clarity and readability. Key changes include:

• Replacing if/else chains with switch statements for DIMM type handling, output processing, metric parsing, and configuration settings.
• Updating several modules (internal/report, cmd/metrics, cmd/config) to use the new switch syntax for improved maintainability.
• Minor improvements in formatting and structure without changing core logic.

• Consider adding a default case to the switch on dimmType to explicitly handle unexpected values and avoid silent failures if a new DIMMType is introduced.
