PR Checklist

• Addresses an existing open issue: fixes 🐛 Bug: --t option for timeout does not work with mocha 12.0.1+. It used to work with mocha 11.7.5 and earlier. #6374
• That issue was marked as status: accepting prs (it is currently marked status: in triage)
• Steps in CONTRIBUTING.md were taken

Overview

The CLI preprocessor left every one-character alias unchanged, including long-form --t, causing 0 to be treated as a positional number instead of the timeout value. This change canonicalizes one-character aliases supplied with a long-option prefix while preserving short-option parsing, and adds coverage for --t 0 and --t=0.
