refactor(pr-53): 调整文件命名和技能定义

1. 回滚 skills/codex/SKILL.md 至使用 codex-wrapper
   - codeagent-wrapper 已由独立技能 skills/codeagent/SKILL.md 提供
   - 保持向后兼容性和职责分离

2. 重命名命令文件为语义化名称
   - gh-implement.md → gh-issue-implement.md
   - 更新命令标识从 /gh-implement 到 /gh-issue-implement
   - 提升命令意图的清晰度

 **Dependencies Best Practices**
 
-- Avoid multiple invocations: Place "analyze then implement" in a single `codeagent-wrapper --parallel` call, chaining them via `dependencies`, rather than running analysis first and then launching implementation separately.
+- Avoid multiple invocations: Place "analyze then implement" in a single `codex-wrapper --parallel` call, chaining them via `dependencies`, rather than running analysis first and then launching implementation separately.
 - Naming convention: Use `<action>_<timestamp>` format (e.g., `analyze_1732876800`, `implement_1732876801`), where action names map to features/stages and timestamps ensure uniqueness and sortability.
 - Dependency chain design: Keep chains short; only add dependencies for tasks that truly require ordering, let others run in parallel, avoiding over-serialization that reduces throughput.
