0.7.8

Added

• User guide in English, Korean, Chinese, Japanese and Spanish (docs/manual/), with numbered screenshots from the
  real plugin, linked from both READMEs. scripts/manual/capture.py <lang> reshoots the
  screenshots by driving Obsidian, so the guide can follow UI changes and new languages.

Fixed

• Citation styles renamed in the CSL repository resolve again: csl: vancouver (now
  nlm-citation-sequence) used to fail and fall back to APA. Unknown ids are looked up in the
  repository's renamed-styles.json.
• Reading view re-renders a note's citations when its csl: style or numbering changes;
  paragraphs whose text had not changed kept their old labels until the note was reopened.
• Superscript styles (Spine, AMA) keep superscript citations through Compile manuscript
  (text<sup>1</sup>, with no space before the number) and Export to Word; the compiled copy
  showed "text 1" and the Word file lost the superscript.
