[Bug] TOC errors when enabled in "yukina" (Astro blog template)

[guo-gy]

Hi WhitePater233,

Thanks for the "yukina" template! I've encountered an issue with the Table of Contents (TOC) when trying to use it with this Astro-based blog template.

Problem:
When I uncomment the code for the TOC feature, it causes errors, and the TOC doesn't display. I expected it to generate correctly.

Question & Offer to Help:
Is this a known bug for "yukina," or am I missing a step specific to its Astro setup? I'm keen to help fix this or contribute to developing the TOC feature if it's incomplete. 💪

Thanks,
guo-gy

Yes, this is indeed a bug, I triggered the crash while debugging a more complex markdown file, so I commented out the plugin for now.
I plan to follow up by adding a sidebar to add post TOC rendering, I'm just too busy with content for school related projects to maintain that project at the moment.
Contributions from you would be very welcome (if it solves the problem well), and I think the feature can be implemented faster if you can help generate the article structure tree.
