v0.12.18-rc2

We have added maintainers to GitHub since 2025-01-09:

• @SylvanFranklin has become a maintainer of the "Editor integration" and "Document Previewing" feature in #1091

After a super long time of development, we have finished an usable typst grammar for VS Code and GitHub. The grammar can now successfully parse all code, markup and math syntax of source files from typst/packages (1200k LoCs) and typst/typst (17k LoCs) without failure. A failure means the grammar produces any visible parse error but the official parser doesn't complain. However, it can still only parse a subset of typst syntax correctly:

• For example, all braces in #if {}=={}{}{} (without spaces) are identified as code braces.
• For example, It hasn't identified the ";" syntax in math calls.
  But I believe it will not affect us much :).

Most importantly, ideally GitHub will use the grammar to highlight typst code on GitHub in next season. It would be appreciated if people could check and test the grammar before GitHub's integration. the grammar and two ways to test it:

• The grammar: https://github.com/michidk/typst-grammar/blob/main/grammars/typst.tmLanguage.json
• Run Grammar's snapshot tests and GitHub's integration tests.
• Install tinymist and check syntax highlight of typst/packages in VS Code Web.
