fix: update cross-repo doc links after Jekyll-to-Hugo restructure

Files in cmd/ examples/ scripts/ referenced docs/guides/ and docs/reference/
which moved to docs/content/docs/guides/ and docs/content/docs/reference/.
A few links to loose files at the docs/ root were updated to their new
location under docs/content/docs/appendix/.
