test(e2e): per-test capture + custom HTML result index

[samutpra]

Summary

• Capture screenshot + video + trace on every Playwright test (was failure-only) and emit a JSON reporter to e2e-results/results.json.
• New dependency-free Node ESM generator (scripts/generate-e2e-index.mjs + pure logic in scripts/lib/e2e-index-format.mjs) reads that JSON, copies each test's artifacts into a self-contained e2e-results/assets/<spec-id>/ folder, and writes e2e-results/index.html — a per-test table grouped by spec file with status badge, thumbnail, inline video, and trace access (show-trace command + deep-link into the Playwright HTML report's trace viewer).
• Wiring: test:e2e:index (regenerate from last run) and test:e2e:full (run suite then generate, ;-separated so it builds even on failures); e2e-results/ gitignored.
• Unit-tested pure logic via node:test (5 tests). Local-only tooling — no app/runtime, CI, or new dependencies.

Spec & plan: docs/superpowers/specs/2026-06-11-e2e-result-capture-index-design.md, docs/superpowers/plans/2026-06-11-e2e-result-capture-index.md.

A final code review caught and fixed a critical bug: the test id is read from the spec object (JSONReportSpec.id), not the test object — otherwise all artifacts collapsed into one assets/unknown/ folder.

Test Plan

• node --test scripts/lib/e2e-index-format.test.mjs — 5/5 pass
• Generator verified against a synthetic results.json (unique per-test asset folders, correct links)
• Missing-results guard exits 1 with a clear message
• Live run (needs DEV backend on :4000): bun run test:e2e:full -- e2e/tests/clusters/cluster-list.spec.ts then open e2e-results/index.html — confirm thumbnail, inline video, and trace link per row
