新增: 模板系统+工作流节点(YAML加载器+GitNode/HTTPNode/NotifyNode)

- template_loader.rs: YAML→DagDef加载器+校验(空节点/未知类型/依赖环/边引用) - GitNode: 分支/checkout/commit/merge/push/status/log(git CLI封装) - HTTPNode: GET/POST/PUT/DELETE(reqwest,30s超时) - NotifyNode: 桌面通知(日志)+ Webhook(飞书/钉钉/自定义) - 8个模板加载器测试+37个节点测试全绿

+//! 通知节点 — desktop(本地日志,后续接 tauri-plugin-notification) / webhook
+//!
+//! - type=desktop:tracing::info! 输出(桌面通知集成延后,见 PROGRESS.md 后续 Sprint)
+//! - type=webhook:POST JSON {title, message} 到 webhook_url
+//!
+//! 节点语义:尽力而为,通知失败不阻断工作流(webhook 发送失败时输出 success=false 但仍 Ok 返回)。
