feat: Claw Code 重命名及架构升级

品牌重塑:
  - Claude Code → Claw Code
  - .claude → .claw 配置目录
  - CLAUDE_* → CLAW_* 环境变量

  新增功能:
  - 多 Provider 架构 (ClawApi/Xai/OpenAI)
  - 插件系统 (生命周期/钩子/工具扩展)
  - LSP 集成 (诊断/代码智能)
  - Hook 系统 (PreToolUse/PostToolUse)
  - 独立 CLI (claw-cli)
  - HTTP Server (Axum/SSE)
  - Slash Commands 扩展 (branch/worktree/commit/pr/plugin等)

  优化改进:
  - Compaction 支持增量压缩
  - 全局工具注册表
  - 配置文件统一为 .claw.json
