From: "Christopher T. Kenny" <ctk44@cornell.edu>
Date: Tue, 2 Sep 2025 03:25:39 -0400
Subject: Add features to typst base template (take 2).

New template variables supported: `thanks`, `abstract-title`, `linestretch`, `mathfont`,
`codefont`, `linkcolor`, `filecolor`, `citecolor`.

Closes #9956, #11076.

(This is a new version of f000fa168bd122fee6e67f5a67bdd6d42d173261 which
was reverted.)
