Lines and checkboxes tidy and warm.

A carrot of order—now reviewers can blink. 🥕

33-33: Break the checklist item into separate lines for better readability.

Line 33 combines the style guide reference and the update-docs agent skill instruction in a single long line. While both references are accurate, splitting them improves clarity for contributors reviewing the template.

In @.github/PULL_REQUEST_TEMPLATE.md at line 33, Split the single long checklist
item into two separate items: one checkbox reading "Follows the [style
guide](docs/CONTRIBUTING.md)." and a second checkbox with the agent instruction
"Try running the `update-docs` agent skill to draft changes while complying with
the style guide (e.g. prompt your agent with `/update-docs` to catch up the docs
for the changes in this PR)." Update the checklist in
.github/PULL_REQUEST_TEMPLATE.md to replace the combined line with these two
distinct lines so each guidance is clear and independently checkable.
