feat: iPet → iAs 完整迁移，Rust 版微信 AI 助手
Phase 1 ✅ CLI 框架 + 配置系统 - clap 子命令: login / listen / send / whoami / usage - config.json + env var 替换 - tracing 日志系统 - state 持久化（auth/runtime 文件存 + PostgreSQL） Phase 2 ✅ 微信通道 - wechat::client — 完整 iLink Bot HTTP API 实现 - 扫码登录（终端二维码 + 轮询状态） - 长轮询 getupdates / 消息收发 / 监听注册 Phase 3 ✅ AI 对话（纯文本 + function calling） - LlmProvider trait: DeepSeek + LM Studio 实现 - SSE 流式解析（text / reasoning / tool_calls delta / usage） - Conversation: 消息历史 + chat / chat_with_tools 工具循环 Phase 4 ✅ PostgreSQL 集成 - app_state（认证 KV 存储） - chat_records（消息收发记录） - llm_usage（Token 用量统计缓存命中率） - user_memories（长期记忆持久化） - pending_approvals（审批确认码） - scheduled_tasks（定时任务表） Phase 5 ✅ 一切皆 Skill（工具系统） - SkillRegistry: 系统 + 用户 skills 双目录合并 - SKILL.md 解析器 + 子进程执行器（stdin JSON → stdout） - 9 个系统 Skills: datetime / weather / search / email / shell / schedule / memos / read_memories / read_summaries - ApprovalManager: High 风险技能 → 确认码审批（透明模式） - High 风险技能：确认码审批（透明模式） Phase 6 ✅ 定时任务调度器 上下文管理 - ChatSession: checkpoint + token budget (28K) + summaries - Token 估算器（中英文自适应） - 12h 空闲 → trigger_idle_summary（不入会话） - Budget 溢出 → trigger_overflow_summary（入会话 + drain 旧消息） - Summarizer: LLM 生成自然语言摘要（fallback 简单截断） - 长期记忆 / 摘要 通过 read_memories / read_summaries 工具按需读取 工具调用日志 + Token 统计 - INFO: 工具名 + 参数 + 结果摘要 - DEBUG: 子进程 exit/stdout/stderr - ias usage --since --until --model 查看用量和缓存命中率
