fix(runner): escape <errors> in results log help to prevent VitePress build error

The `--execution-messages` help text contained a raw `<errors>` tag that
VitePress' Vue parser interpreted as an unclosed HTML element, breaking
the generated `cli.md` docs page. Wrap it in backticks so it renders as
inline code and is ignored by the template compiler.
