Add --public and --name repository filters

[timgentry]

Summary

Extends the audit_github exec command with two new repository filters and tidies up the existing ones:

• --public — restrict the audit to public repositories only (rejects private repos).
• --name foo bar — filter to one or more repositories by name; implies the whole organisation, so --all isn't needed alongside it.
• Renamed --all-repos → --all for consistency with the other flags.
• Refactored the inline repository filtering into discrete, single-purpose Thor steps (filter_all_if_specified, filter_by_name_array_if_specified, filter_by_topic_if_specified, filter_by_visibility_if_specified).
• Updated the README and CHANGELOG to document the new flags.

Why merge this here

This work has already been rolled into the main way_of_working gem (v2.1.0), where the GitHub audit now lives as a built-in, opt-in feature. This repository is being archived.

These changes are being merged for completeness, so main reflects the final state of the standalone gem before it is retired. No further development is expected here.
