feat(voyage): vendor markdown-it/highlight.js + playground render-pipeline + scripts/render-artifact.mjs CLI — v4.2 Step 8 [skip-docs]

Vendored libs (locked headless via scripts/vendor-playground-libs.mjs;
plan-critic B3 — never use highlightjs.org website builder):
  - playground/lib/markdown-it.min.js           — markdown-it@14.1.0 UMD bundle
  - playground/lib/markdown-it-front-matter.min.js — markdown-it-front-matter@0.2.4 IIFE-wrapped
  - playground/lib/highlight.min.js             — highlight.js@11.11.1 (5-lang bundle:
                                                   yaml/json/javascript/bash/markdown/diff)
  - playground/lib/VENDOR-MANIFEST.json         — pin record + audit trail

scripts/vendor-playground-libs.mjs implements the reproducible
CommonJS-to-IIFE wrapping. Re-vendoring requires only:
  node scripts/vendor-playground-libs.mjs

Render pipeline in playground/voyage-playground.html (~330 LoC total):
  - inline <script src=lib/...> for the three vendored bundles
  - markdown-it init with html: true (preserves voyage:anchor comments)
  - front-matter plugin with pre-render-then-wrap pattern (research/03)
  - paste-import-row textarea + Render/Sample/Clear buttons
  - voyage-viewport region with role + aria-live for A11Y
  - localStorage key pattern: voyage_ann_<project>__<slug> (risk-assessor H7)
  - inline sample plan (mirrors annotation-plan.md fixture)

scripts/render-artifact.mjs CLI (~200 LoC) — brief SC1 + SC11:
  - reads input.md, runs same vendored pipeline server-side
  - inlines DS CSS + (URL-stripped) highlight.js into output
  - zero http://https:// URLs in output (verified by test)
  - deterministic: two invocations -> byte-identical sha256
  - default output: <input>.html next to input

Test coverage:
  - tests/scripts/render-artifact.test.mjs — 5 cases (SC1/SC11)
  - tests/playground/voyage-playground.test.mjs — +5 cases (Step 8 extension)

Verify: node --test tests/playground/voyage-playground.test.mjs
       tests/scripts/render-artifact.test.mjs -> 18 pass / 0 fail.
Full npm test: 587 pass / 0 fail / 2 skipped (Docker).

# Demo plan for annotation round-trip
This sample mirrors `tests/fixtures/annotation/annotation-plan.md` so the
playground first-run shows a complete round-trip-able artifact.
## Implementation Plan
### Step 1: Touch a sentinel file
- **Files:** `tmp/sentinel-1.txt` (new)
- **Verify:** `test -f tmp/sentinel-1.txt`
- **Manifest:**
```yaml
manifest:
expected_paths:
- tmp/sentinel-1.txt
min_file_count: 1
```
## Verification
- `npm test` passes.

#!/usr/bin/env node
// scripts/vendor-playground-libs.mjs
// Reproducible vendor script for v4.2 playground render-pipeline.
//
// Usage: node scripts/vendor-playground-libs.mjs
//
// Pins (locked per plan-critic B3 — never use highlightjs.org website builder
// or any other interactive UI; this script is fully headless):
// - markdown-it@14.1.0 (UMD bundle copied verbatim)
// - markdown-it-front-matter@0.2.4 (CommonJS module wrapped in IIFE)
// - highlight.js@11.11.1 (5-lang bundle assembled from CommonJS sources)
//
// Output: playground/lib/{markdown-it.min.js, markdown-it-front-matter.min.js,
// highlight.min.js}
//
// All three output files are zero-network browser-loadable scripts that
// expose globals (`window.markdownit`, `window.markdownitFrontMatter`,
// `window.hljs`). They also work under Node.js dynamic-import via the
// pattern in scripts/render-artifact.mjs (UMD + global-eval).
