Not all operating systems have /tmp folder. Is there another way to show the debug log?

This doesn't seem to be related to latex.

Is it possible to keep the comments and existing code for parsing html?

This is perhaps a useful functionality, but too many parts of the code are being changed at once. Please let me take some time to review the code and test. |

Add KaTeX/LaTeX equation rendering
When pasting from Claude.ai or copilot or other sites that use KaTeX, LaTeX equations are now automatically rendered to PNG and embedded as images in Zim.
How it works: the parser detects tags inside KaTeX HTML, extracts the raw LaTeX source, and renders it to PNG via latex/dvipng (the same tools used by Zim's built-in Equation Editor plugin). The PNG is saved to the page's attachments folder and embedded as {{./eq_....png}}.
Requirements: latex and dvipng must be installed (same dependency as Zim's Equation Editor plugin).
Also included: a few minor fixes (hr tag parsing, Umlaut normalization, regex multiline flags, dash escaping).
