feat: Phase4 命令系统与上下文增强

新增基础设施: - TokenTracker: 真实Token使用量追踪和费用估算（按模型定价） - SkillLoader: .claude/skills/ 扫描加载，支持YAML frontmatter元数据 - GitContext: Git分支/状态/最近提交收集，注入系统提示词新增命令 (4个): - /init: 项目CLAUDE.md初始化向导，自动检测项目类型(Maven/Gradle/Node/Python等) - /status: 会话状态仪表板（模型、Token、内存、运行时间等） - /context: 上下文概览（CLAUDE.md、Skills、Git、系统提示词大小） - /config: 配置查看/设置（支持model快捷切换和API key显示）增强命令 (3个): - /cost: 从占位→真实Token统计，显示input/output/cache tokens和费用 - /model: 支持快捷名称切换(sonnet/opus/haiku)，显示可用模型列表 - /compact: 增强显示压缩前后消息数和Token使用量系统提示词增强: - 集成Skills摘要和Git上下文到系统提示词 - 新增Shell环境信息和更详细的Guidelines 命令总数: 6 → 10, 工具总数: 11 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
