Add docs/go.sum (Hextra v0.12.3 checksums) produced by hugo mod tidy.
Update docs/go.mod with the resolved module version.
Ignore docs/.hugo_build.lock, docs/public/, and docs/resources/ —
all are generated by Hugo locally and not needed in the repo.

Replace docs/_config.yml + docs/SUMMARY.md with Hugo + Hextra theme.
Move all content into docs/content/, images into docs/static/images/.
Update docs_consistency_test.go to check Hugo front matter instead of
SUMMARY.md inclusion. Update CI workflow and screenshot script paths.
