Final code review and quality gate — run tests, check coverage, audit security, verify acceptance criteria from spec, and generate ship-ready report. Use when user says "review code", "quality check", "is it ready to ship", "final review", or after /deploy completes. Do NOT use for planning (use /plan) or building (use /build).

最终代码审查与质量门禁——运行测试、检查覆盖率、审计安全性、验证规范中的验收标准，并生成可发布报告。当用户输入“review code”“quality check”“is it ready to ship”“final review”或/deploy执行完毕后使用。请勿用于规划（使用/plan）或构建（使用/build）。
