feat: Provider model_settings 全链路 + 监管节点工具集 + 重型插件注入 + 前端打磨

- Provider model_settings (Provider+Model 级别参数配置): DB JSONB → API → GSM → AgentFactory.resolve → 三节点 agent.run 注入
- 新增 data/toolset/regulatory_toolset/: 监管节点专属工具（query_workflow_status / query_task_list / send_file）
- send_file 从 interactive_toolset 迁移至 regulatory_toolset，interactive 仅保留 approval
- mcp_helper 合入 GlobalPluginManager dispatch tools
- 前端 Provider 弹窗参数设置区加 JSON 编辑器（model_settings）
- 前端 Plugin 页面新增"重型插件"Tab（HeavyPluginList 占位）
- .gitignore 精简：去除系统默认项，修复 data/ 子目录追踪
- data/toolset/ 与 data/plugin/ 首次纳入版本控制
