- Review Robocop and Robotidy for additional rules

Start by reviewing the linked Robocop rules and comparing the available Robotidy rules for keyword-level guidance. Define which rules should be covered, including limits on calls, loops, conditionals, data creation, naming, documentation, and keyword length. Done means the selected rules are clearly documented and additional relevant rules from both tools have been reviewed.
