test(browser-skills-e2e): exercise dispatch with bundled hackernews-frontpage

Covers the full \$B skill list/show/test pipeline against the real bundled reference skill (defaultTierPaths picks up <repo>/browser-skills/). Verifies frontmatter shape, the three-tier walk surfaces the bundled entry, and \$B skill test successfully runs the bundled script.test.ts in a child bun process. \$B skill run end-to-end against the live network is intentionally NOT covered here (would be flaky against news.ycombinator.com); the spawn lifecycle is exercised in browser-skill-commands.test.ts using inline synthetic skills.

+/**
+ * browser-skills E2E — exercise the full dispatch path against the bundled
+ * `hackernews-frontpage` reference skill. Verifies:
+ *
+ *   - $B skill list resolves the bundled tier and surfaces hackernews-frontpage
+ *   - $B skill show returns the SKILL.md
+ *   - $B skill test runs script.test.ts (which itself runs against the bundled
+ *     fixture) and reports pass
+ *
+ * Coverage gap intentionally NOT here: $B skill run end-to-end against the
+ * bundled skill goes to live news.ycombinator.com and would be flaky. The
+ * spawnSkill lifecycle (env scrub, scoped token, timeout, stdout cap) is
+ * already covered by browse/test/browser-skill-commands.test.ts using inline
+ * scripts.
