docs: update maturity scorecard - #95933

I manually ran "all" qa profile action and used that evidence to generate this locally using the maturity scorecard renderer locally. Run 28000996256.

What Problem This Solves

OpenClaw has a current maturity taxonomy and QA profile evidence artifact, but the public scorecard needed to be regenerated from full taxonomy evidence instead of the older release-profile evidence subset.

Why This Change Was Made

• Regenerates qa/maturity-scores.yaml from the current active taxonomy using the newer committed source shape for Quality, Completeness, and LTS review state.
• Renders docs/maturity/scorecard.md and docs/maturity/taxonomy.md from the QA Profile Evidence all artifact from run 28000996256.
• Updates the maturity renderer to prefer all scorecard evidence for Coverage while retaining release fallback for non-workflow/manual use.
• Changes the generated maturity scorecard workflow default from release to all, with guard coverage so future generated scorecard PRs use full taxonomy evidence.
• Adjusts the maturity taxonomy renderer so generated family index headings do not duplicate the later detail headings under markdownlint.

User Impact

Readers get initial public maturity scorecard and taxonomy pages backed by the latest score source and full taxonomy QA evidence summary. The scorecard no longer shows Unscored for overall Coverage just because release profile membership omits many categories; it now shows the low but complete full-taxonomy coverage state from the all profile artifact.
