MarkEdit Textpack Export v0.2.0

This release addresses the three edge cases identified during review of the initial registry submission:

• Escape rewritten asset filenames in Markdown links and quoted HTML attributes, including parentheses and apostrophes.
• Match the real HTML src and href attributes instead of data-src or data-href.
• Preserve query strings and URL fragments when rewriting local links, such as guide.md#introduction.
• Add Traditional Chinese throughout the extension's menu and export messages, while retaining English and Simplified Chinese support.
• Add regression tests for the built distributable and the reviewed edge cases.

Verified with 12 automated tests and manual MarkEdit exports in English and Traditional Chinese. Both exported Textpack archives passed ZIP integrity checks, and the bundled screenshot assets matched the originals byte-for-byte.

Thanks to @cyanzhong for the thoughtful review and actionable suggestions.
