[Feature] Metadata-Only Output

[jlucaso1]

An option (maybe --metadata-only) to output just the summary, directory structure, and file metrics without the content, useful for quick analysis.

That would be very useful, and also a parsable json format to integrate with other tool (like repomix runner extension)

maybe a --report and --report-json flags ?

Thanks for the suggestion!

We actually already have boolean options like output.fileSummary and output.directoryStructure, so for consistency, adding an output.files option seems like a good fit.

If files is set to false, only the metadata and directory structure will be included in the output.

We can also add a corresponding CLI flag --no-files, similar to the existing --no-file-summary and --no-directory-structure flags.
