feat: QA restructure, browser ref staleness, eval efficiency metrics (v0.4.0) (#83)

* feat: browser ref staleness detection via async count() validation resolveRef() now checks element count to detect stale refs after page mutations (e.g. SPA navigation). RefEntry stores role+name metadata for better diagnostics. 3 new snapshot tests for staleness detection. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: qa-only skill, qa fix loop, plan-to-QA artifact flow Add /qa-only (report-only, Edit tool blocked), restructure /qa with find-fix-verify cycle, add {{QA_METHODOLOGY}} DRY placeholder for shared methodology. /plan-eng-review now writes test-plan artifacts to ~/.gstack/projects/<slug>/ for QA consumption. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: eval efficiency metrics — turns, duration, commentary across all surfaces Add generateCommentary() for natural-language delta interpretation, per-test turns/duration in comparison and summary output, judgePassed unit tests, 3 new E2E tests (qa-only, qa fix loop, plan artifact). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: bump version and changelog (v0.4.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: update ARCHITECTURE, BROWSER, CONTRIBUTING, README for v0.4.0 - ARCHITECTURE: add ref staleness detection section, update RefEntry type - BROWSER: add ref staleness paragraph to snapshot system docs - CONTRIBUTING: update eval tool descriptions with commentary feature - README: fix missing qa-only in project-local uninstall command Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: add user-facing benefit descriptions to v0.4.0 changelog Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
