Pin Hugo version to 0.164.0

hugo-version: 'latest' meant build success depended entirely on whatever Hugo release was current at build time. Hugo v0.165.0 (released ~2026-08-12) broke resolution of nested-path shortcode names used by every tutorial page in this pipeline, breaking the production build with no corresponding content change. Pinned to the last confirmed-good version.
