This pull request refactors the trademark checking logic for plugin names and slugs to improve accuracy and code maintainability. The main change is the introduction of a generalized has_trademark method, which replaces the previous slug-specific logic and adds word boundary checks for plugin names to reduce false positives like. For example the current version of the plugin flags the acronym WCAG for the use of WC. Helper methods have also been added for clarity and future extensibility.

Trademark checking logic improvements:

• Introduced a new has_trademark method that checks for trademarked terms in both plugin names and slugs, with an option to use word boundaries for names to avoid false positives.
• Updated validate_name_has_no_trademarks and validate_slug_has_no_trademarks to use the new has_trademark method, passing the appropriate word boundary flag for each case [1] [2].

Code organization and maintainability:

• Added helper methods has_trademarked_slug and has_trademarked_name that delegate to has_trademark with the correct parameters, improving code readability and future extensibility.
• Updated method and docblock names to reflect the more generalized trademark checking and new versioning.
