Subject: [PATCH] Install official Typst binary and use it for .typ compilation

Quarto bundles a modified Typst fork that lacks --synctex, making
bidirectional sync impossible. Install the official Typst binary
(v0.13.1) from upstream and use it in TypstRunner instead.

This also means .typ projects now use the unmodified Typst compiler,
which is correct since TypstRunner handles plain .typ files (not .qmd).
QuartoRunner continues to use Quarto's bundled Typst internally.
