Skill、流式执行优化与系统架构全面升级

  本次提交对标 Claude Code 与 Hermes-Agent 的工程细节，在安全、可靠性、
  会话管理、自我进化四个维度进行了系统性加固，变更总量 48 文件 / +12680 -2292 行。

  ═══════ 安全纵深防御 ═══════

  1. Hardline 硬阻止层 (src/agent/runtime/hardline.rs, +534 行)
     - 不可绕过的危险命令拦截（关重启、磁盘擦除、Fork 炸弹、rm -rf /、kill -1）
     - 反规避标准化管线: ANSI 序列剥离 → Unicode NFKC → shell 反斜杠还原 → 空字面量清理
     - 在 PermissionChecker 之前执行，YOLO/Bypass 模式下同样生效
     - 集成到 executor Phase 2，被拒绝工具直接注入错误结果

  2. Permission 优先级裁决器 (src/agent/runtime/permission.rs, +200 行)
     - 7 层正式优先级规则 (P0 Deny → P7 Allow)，带冲突日志
     - explain() 方法支持审计追溯
     - Hook PermissionRequired 与 Checker 结果的正确叠加逻辑

  ═══════ Checkpoint 文件快照系统 ═══════

  3. git2 原生快照 (src/agent/runtime/checkpoint.rs, +920 行)
     - 基于 git2 bare repo，内容寻址自动去重
     - 文件变更操作前自动触发 (file_write/file_edit/run_bash)
     - 每目录每 turn 最多一次快照，防止同一轮重复
     - 支持 list/diff/restore API + pre-rollback 安全快照
     - 旧快照自动 prune（保留最近 N 个）+ 按目录隔离 ref
     - 排除规则自动过滤 node_modules/target/.git/*.pdf 等
     - 集成到 executor: 文件操作前 ckpt.ensure_checkpoint()

  ═══════ 错误恢复系统大升级 ═══════

  4. 21 种 FailoverReason 分类 (src/agent/runtime/error_recovery.rs, +1200 行)
     - 参考 Hermes-Agent error_classifier.py
     - 8 步分类管线: provider-specific → HTTP status → text pattern → error body → fallback
     - is_retryable / should_compress / should_failover / is_permanent 方法
     - Context Overflow 自动修复: 从错误消息提取 token 限制，自动下调预算
     - RecoveryStep::AdjustMaxTokens 实现 (参考 Claude Code 自动修复)
     - 向后兼容 ErrorKind 别名

  ═══════ 会话 Rewind / Branch / Retry 体系 ═══════

  5. 完整 undo 栈 (src/agent/runtime/session.rs, +800 行 + 2 迁移脚本)
     - Rewind (软删除): active=0 标记，审计 trail 保留，LLM 不可见
     - Restore (撤销回退): 冲突检测——回退后有新消息则拒绝，引导使用 Branch
     - Branch: 分叉会话，复制所有 active=1 消息到新会话
     - Retry: 硬删除最后一轮对话，返回原消息文本供前端重提交
     - 数据库: agent_messages.active 列 + agent_sessions.rewind_count + parent_session_id
     - API: 4 个新端点 (/branch, /retry, /rewind, /rewind/restore)
     - load_history_for_agent 全面使用 active=1 过滤

  ═══════ Hooks 系统模块化重构 ═══════

  6. 单文件 → 7 模块体系 (src/agent/hooks/)
     hooks.rs (994 行) 拆分为:
     - mod.rs    — 入口 + HookRegistry + SessionHookManager
     - types.rs  — 类型定义 (Context, TaggedContext, PermissionRequestAction 等)
     - traits.rs — AgentHook + AsyncAgentHook + 15 种生命周期事件
     - matcher.rs — 工具名/参数匹配 + session 作用域过滤
     - dispatch.rs — 并行调度引擎 (run_pre/post_tool_use 等)
     - registry.rs — 注册/注销/查询
     - builtins.rs — CancellationHook + MetricsHook + AuditLogHook + ContextDeduplicator

     关键改进:
     - run_pre_tool_use 并行执行所有匹配 hooks，聚合 Block/MutateInput/Continue
     - TaggedContext 带完整来源标记的上下文注入 (hook_name + event)
     - ContextDeduplicator 单 dispatch cycle 内内容哈希去重
     - AsyncAgentHook 支持 fire-and-forget 异步 hooks

  ═══════ Executor 并发执行升级 ═══════

  7. 三阶段管道重写 (src/agent/runtime/executor.rs, +600 行)
     - Phase 1: 死循环检测 + 参数解析 (不变)
     - Phase 2: Hardline 预检查 (新增) → PermissionChecker (改进)
     - Phase 3: ToolPartitioner 分区 → 逐批次执行 (重写)
       - 并行批次内 FuturesUnordered 并发
       - 串行批次确保非并发安全工具独占执行
       - Checkpoint 预触发集成
     - Hook 上下文注入: system-reminder 格式 + ContextDeduplicator 去重
     - Hook 阻塞错误详细记录

  ═══════ 流式执行真正的流式调度 ═══════

  8. StreamingExecutor 重写 (src/agent/runtime/streaming_executor.rs, ~400 行变更)
     - on_tool_use 中对并发安全工具立即 tokio::spawn，不等待 flush
     - executing_non_concurrent 标志阻塞后继工具直到独占工具完成
     - JoinHandle 管理替代自定义 cancel channel
     - completed_queue 按流顺序 yield
     - Sibling Abort 通过 broadcast channel + tokio::select! 竞速
     - ToolContext 实现 Clone (支持 per-task 上下文复制)

  ═══════ 自改进 Skill 系统 ═══════

  9. PatternDetector + SkillCreator + Curator (src/agent/skills/, +1500 行)
     - PatternDetector: 扫描 agent_messages 表，检测跨 session 重复工具调用模式
     - SkillCreator: 将高置信度模式自动生成 SKILL.md (YAML frontmatter + 工作流步骤)
     - SelfImprovePipeline: 一站式 模式检测 → 创建 → 质量审查
     - Curator: 分析 skill 使用统计，标记 stale/deprecated，建议清理
     - Skill frontmatter 新增 pinned 字段 (禁止 Curator 自动清理)

  ═══════ 基础设施优化 ═══════

  10. 系统提示词缓存 (src/agent/runtime/system_prompt.rs + mod.rs)
      - SystemPromptCache: 首次计算后永久复用，/clear 时失效
      - 新增 SAFETY / SYSTEM_CONTEXT / TOOL_USAGE 静态 section
      - 环境/tools/skills/memory 动态 section 通过 get_or_compute 缓存

  11. ToolRegistry schema 缓存 (src/agent/tools/mod.rs)
      - schema_cache + schema_generation 版本号
      - 工具变更/过滤器变更时自动失效
      - precompute_definitions() 预计算 (AgentRuntime 初始化时调用)

  12. 迭代摘要融合 (src/agent/compact.rs, +100 行)
      - 参考 Hermes context_compressor.py
      - CollapseLog 追踪压缩历史，支持溢出合并
      - extract_prior_summary: 提取已有摘要融入新压缩

  13. SubAgent 系统提示词模块化 (src/agent/tools/subagent.rs)
      - 复用 5 个标准 section + 子代理专有上下文 section
      - 独立 ToolRegistry 构建工具列表

  ═══════ 前端 — CSS 变量主题系统 ═══════

  14. 全新主题变量体系 (dashboard/src/index.css + App.tsx + 各面板)
      - CSS 自定义属性: --bg-card, --text-main, --text-muted, --border-precision
      - 语义化颜色: --accent-blueprint, --accent-star
      - 全面替换硬编码 Tailwind 颜色 (slate-xxx → var(--xxx))
      - 文献入库提示优化 ("核心知识节点" 替代 "向量块")
      - ReaderPanel 样式变量化
