feat(scaffold): redesign paper scaffold + clarify doc responsibilities
Scaffold (mytoolkit init paper):
- default to portable Elsevier elsarticle [review,3p,11pt] (was ctexart/Fandol)
- TeX Live Libertinus fonts (serif+math+mono), no system-font dependency
- xelatex one-engine via latexmk; figure/abstract/keyword frontmatter
- PDF bookmarks expand to two levels (bookmarksopenlevel=2)
- fix diffpreamble.dtx: define \DIFadd/\DIFdel (latexdiff highlighted now compiles)
Docs responsibility split:
- CLAUDE.md owns design decisions/constraints; exact scaffold specs live only
in the generated main.tex header (self-documenting, no drift)
- README/SKILL point to those; README command table gains `voice`
- reconcile source-of-truth wording across CLAUDE.md / README / SKILL
