Research direction

Look for the CLI argument parsing logic, likely in src/main.rs or a dedicated cli module. The flag should read the final configuration after merging defaults, .gitignore, and command-line arguments. The output should be printed to stdout. Check existing tests for CLI behavior to see how to add a test for the new flag.

Written by the indexing model from the issue text.

Description

I want to suggest adding a -d CLI flag which (initially) dumps the effective flags.
This should reflect the final setting, after evaluating .gitignore, CLI arguments and anything else.

In my case, I am unsure if my max_line_length of 120 is picked up or not but can not verify as the tool does not show what it is working with currently.

Future:
In the future this could be enhanced to a full fledged debug mode flag, which would print more diagnostic data and reasoning why lines are altered.
