新增项目管理：可在 Web 端创建、编辑、归档项目，按项目归类对话与漏洞；支持项目黑板（共享事实），在多轮会话间沉淀目标、环境、认证等认知，并自动注入 Agent 上下文；Agent 可通过 MCP 工具（如 upsert_project_fact、get_project_fact）读写黑板，便于长期渗透测试任务的上下文延续。
Added project management: create, edit, and archive projects in the Web UI; group conversations and vulnerabilities by project. Shared facts (project blackboard) persist cross-session context (targets, environment, auth notes) and are auto-injected into agent prompts. Agents can read/write the blackboard via MCP tools (e.g. upsert_project_fact, get_project_fact) for continuity across long-running engagements.
