Enhance dictionary with front-end terms

During web integration for the assignment, fmtscan flagged three
front-end terms - 'href', 'monospace', and 'rel' - as spelling
errors. This echoes a similar issue noted in #265. Add these valid
technical terms to the dictionary to prevent false positives,
ensuring accurate code validation. This resolves the false flagging
noted in #265 but does not address its call for enhanced error
reporting in fmtscan.
