Add pbakaus/impeccable (v4.1.1, 23 design commands, 59 deterministic
anti-slop rules) to the frontend workflow and READMEs.
Document the QA harness measurements in both READMEs: before/after
workflow scores on the same ruler (total +98.6%), the four green gates,
the meta-tests, and what the refinement added. Full snapshot history
is in qa/snapshots/.
Two versions (EN primary, PT-BR). Hero with badges, TOC, per-skill
explanations with links to each skill's owner, security rationale,
quick start, QA harness section and repo layout.
Removed AI-isms and em-dashes flagged by avoid-ai-writing checks.
