feat(multi-agent): 子智能体系统升级

- prompt改造：子智能体注入AGENTS.md/执行环境/工作区信息/skills/项目记忆
- 工具增加：read_skill/recall_project_memory/todo_create/todo_update_task/save_webpage
- 上下文压缩：深度压缩机制，记录current_context_tokens，默认150k阈值可配置
- 模型升级：sub_agent_models.json支持thinkmode_status/extra_parameter，与主智能体对齐
- 角色管理三层结构：源码树预设multi_agent_roles/ + 运行态host/web预设 + web按用户隔离
- 启动同步：initialize_system调用sync_preset_roles同步预设到host和web运行态
- 模式判断：API用session.host_mode，工具用data_dir路径判断，不依赖IS_HOST_MODE
- 前端：个人空间新增子智能体管理页(角色CRUD/压缩阈值/模型选择)，复用个人空间样式
- 入口改造：登录页移除多智能体按钮，QuickMenu加模式切换项，运行中对话禁止切换
- 工具调整：多智能体模式create_sub_agent去掉timeout/deliverables_dir参数
- skill禁止：sub-agent-guide在多智能体模式下禁止阅读
- .agents/统一为.astrion/路径修复

+启动时调用 `sync_preset_roles()` 把源码树预设同步到 host 和 web 两个运行态预设目录。
 
-角色目录：
+**重要**：本模块不再依赖 `IS_HOST_MODE` 判断运行模式。
-- ~/.astrion/astrion/host/mutiagents/agents/<role_id>.md
+调用方（API / tools_execution）通过参数显式传入 `runtime_dir` 和 `custom_dir`：
-
+- 不传则仅扫描源码树预设（最小安全回退）
-存储约定见 .astrion/memory/multi_agent_mode_design.md。
+- host 模式：`runtime_dir` 和 `custom_dir` 指向同一目录
+- web 模式：`runtime_dir` 指向 web 预设目录，`custom_dir` 指向用户个人目录
