WorldBase v1.6.8

🚀 New Features

• Document drafts with fidelity-preserving edits: AI edits are staged as drafts with a detailed change list and data-loss risk markers; originals stay untouched until you apply them. Office files keep their media and styling.
• Redesigned workspace panel: tabbed workspace (browser, documents, folders, terminal, project apps); new open_workspace_tab tool lets the AI open folders, documents or URLs for you; new Excel/PPT HTML previews with caching.
• Terminal integration: built-in terminal tab with tools for the AI to read from / write to the active terminal session.
• Project server management tools: start/restart project servers; create_project now prevents duplicate projects within one run.

⚡ Architecture & Performance

• More tools flipped to native Rust execution (command execution, project database query/analysis) with identical permission grading, timeouts, process-tree cleanup and command-history semantics; SQLite opened read-only. Tool contract snapshot 69→43.
• Module split (ai-host / ai-harness / document-workbench), removed unused image-generation service, added embedding model probing, improved scheduler durable-ID handling.

🛠 Fixes

• Plan mode: now intercepted at the execution layer — after exiting plan mode the same turn can continue executing; no longer falls back into plan mode next turn, and the model no longer misjudges project creation as unavailable.
• OpenCode: fixed missing session header (thanks @skypeee, PR #101).

🔧 Build/CI

• Hot payload signing secrets wired into CI (unsigned payloads fail the build), workflow trigger tweaks, release artifact filtering.

🚀 新功能

• 文档草稿机制(保真编辑)：AI 编辑文档时先生成草稿并逐项列出变更与数据丢失风险标记，原始文件在你确认应用前保持不变；对 Word/Excel/PPT 采用保真操作，保留原有媒体与样式；禁止对导入文档和已有 Office 文件直接覆写。
• 工作区面板重构：新增统一的标签页式工作区(浏览器、文档、文件夹、终端、项目应用)，AI 可通过新的 open_workspace_tab 工具帮你打开文件夹、文档或网页；Excel/PPT 新增 HTML 预览并带预览缓存。
• 终端集成：新增内置终端标签页，AI 可读取/写入当前活动的终端会话。
• 项目服务器管理工具：新增启动/重启项目服务器的工具;create_project 会防止同一轮对话中重复建项目。

⚡ 架构与性能

• 更多工具翻转为 Rust 原生执行：命令执行(run/get_project_command、run/get_workspace_command)与项目数据分析(query_project_database、analyze_project_data)迁移至 Rust,权限分级(safe/risky/deny)、超时转后台、进程树清理、命令历史等语义与 Node 版逐字段一致；SQLite 只读打开更安全。工具契约快照 69→43。
• 模块整理：ai-engine 拆分为 ai-host / ai-harness / document-workbench,职责更清晰；移除未使用的图像生成服务；新增 Embedding 模型探测；定时任务调度器改进持久化 ID 处理。

🛠 修复

• 计划模式：改为执行层拦截而非隐藏写工具——退出规划模式后同一轮即可继续执行；修复退出后下一轮又回到规划模式的问题；避免模型误判“无法新建项目”而引导用户走不存在的入口。
• OpenCode 会话头缺失：修复 OpenCode provider 缺失会话头的问题(感谢 @skypeee 的 PR #101)。

🔧 构建/CI

• 热更新载荷签名密钥注入 CI,未签名载荷直接使构建失败；调整工作流触发规则；过滤 release 产物。
