v0.34.1

Two blume validate findings from the first run of tools/docs-site.sh over a full report set.

Fixed

• Docs site. A section-number anchor in a report link (scalardb-schema.md#9.5 — the shape
  rules/architecture-decision-records.md allows in upstream) is not a Blume heading slug and
  produced a broken link on every ADR provenance line; a purely numeric anchor now resolves to the
  page. Nested report directories (adr/, aggregates/, state-machines/, …) get distinct
  sidebar orders instead of all falling back to alphabetical, and a directory that has its own
  index page is labelled by that page's title so the sidebar and the page agree.
