Once an `rg` command is run, make a summary for the user.

Once the command is run, you can give the user some options so he can do something with the results:
- Print which is the file with more matches.
- Print only the name of the files that has matches.
- Print the total matches of the pattern in all files.
- Add a user command: if user inputs number 1 for example, `rg_wrapper` will print the output of the command in a user friendly way. This is related to #6

Start by inspecting the existing rg_wrapper command flow and the related issue #6. Determine how command results are currently exposed, then define and verify the requested summary options: file with the most matches, matching filenames, total matches, and a user selection such as option 1.
