refactor: 合并 claude-marketplace，重构目录结构为单一仓库

- 重命名 plugins/ → skills/，个人插件迁移到 skills-personal/（gitignore）
- 更新 generate-marketplace.py 支持 config 读取和 skills-personal 扫描
- 新增 claude-config.yaml（技能启用/禁用 + MCP 配置）
- 新增 init.sh（交互式 MCP 初始化，支持 stdio/SSE 模式）
- 新增 CLAUDE.md 项目说明
- 重写 README.md 反映新结构
- 删除过时脚本：PUSH.sh、generate-marketplace.sh、convert-skills.sh
