Enhance log readability by adding analysis details (classes processed, counts, etc.)

Current logs lack clarity about analysis details. We should add information like the number of classes processed and their names to make `log` output more informative and easier to understand.

Start by locating the `log` output and the analysis entry point in the Go command-line tool. Trace where classes are processed, then define the added class names and count in the log output. Done means the logs clearly report the analysis details and the relevant existing checks still pass.
