Rename tools/ to _tools/ so Quarto excludes it from render targets

The underscore prefix convention (_extensions, _freeze, _site) tells
Quarto to skip the directory automatically, replacing the explicit
render exclusion and the render: block (defaults suffice). Also removes
an orphaned freeze cache for typst.qmd which had no executable cells.
