feat(deepdata): 引入修改密码、文件预览组件与清洗算子增强，deepflow 改名为 deep-flow

本次同步 09-12 至 09-28 的代码变更，主要内容：

新增功能
- 修改密码：后端新增 ChangePasswordRequest DTO 与UserController/UserService
  对应接口，前端新增 ChangePasswordDialog 并在 Header 接入入口
- 文件预览组件重构：file-preview 目录拆分出 VideoPreview（支持 blobUrl 直传）、
  ImagePreview、AudioPreview，index.tsx 统一调度各类型预览器
- 新增 my_ops 算子模块：markitdown_parser、mineru_pdf_parser、text_quality_evaluator
- 新增 tools/minio-file-server MinIO 文件服务

功能增强
- 数据清洗：cleaning_task_service/scheduler/routes 重构，
  data_juicer_executor 与 wrapper 增强，OperatorTable/LogsTable/TaskDetail 同步调整
- 数据标注：annotation sync.py、project.py 接口与schema 更新
- 数据采集、算子市场、首页与菜单路由相关页面调整
- DataJuicer 算子接入（useOperatorOperations、dj_ops_schema）

结构调整
- deepflow/ 更名为 deep-flow/（419 个文件重命名）
- 新增 helm 部署编排、GitHub Actions 之外的自建镜像构建脚本

未纳入本次提交
- scripts-backup/、runtime/python-executor-backup/、components_backup/（备份目录）
- *.backup*、__pycache__ 产物
- zh_core_web_sm-3.8.0-py3-none-any.whl（46MB 构建产物）
- DataX/（内嵌独立仓库，远程亦未收录其源码）

+# DeepFlow Service
+
+## Overview
+
+DeepFlow is an LLM-driven service for planning and reasoning tasks, supporting multiple LLM providers.
+
+## Architecture
+
+```
+runtime/deep-flow/
+├── conf.yaml       # DeepFlow configuration file
+├── .env            # Environment variables
+└── (other source code)
+```
+
+## Configuration
+
+### Basic Configuration (conf.yaml)
+
+```yaml
+# Basic model configuration
+BASIC_MODEL:
+  base_url: https://api.example.com/v1
+  model: "model-name"
+  api_key: your_api_key
+  max_retries: 3
+  verify_ssl: false  # Set to false if using self-signed certificates
+
+# Reasoning model configuration (optional)
+REASONING_MODEL:
+  base_url: https://api.example.com/v1
+  model: "reasoning-model-name"
+  api_key: your_api_key
+  max_retries: 3
+
+# Search engine configuration (optional)
+SEARCH_ENGINE:
+  engine: tavily
+  include_domains:
+    - example.com
+    - trusted-news.com
+  exclude_domains:
+    - spam-site.com
+  search_depth: "advanced"
+  include_raw_content: true
+  include_images: true
+  include_image_descriptions: true
+  min_score_threshold: 0.0
+  max_content_length_per_page: 4000
+```
+
+## Supported LLM Providers
+
+#### OpenAI
+```yaml
+BASIC_MODEL:
+  base_url: https://api.openai.com/v1
+  model: "gpt-4"
+  api_key: sk-...
+```
+
+#### Ollama (Local Deployment)
+```yaml
+BASIC_MODEL:
+  base_url: "http://localhost:11434/v1"
+  model: "qwen2:7b"
+  api_key: "ollama"
+  verify_ssl: false
+```
+
+#### Google AI Studio
+```yaml
+BASIC_MODEL:
+  platform: "google_aistudio"
+  model: "gemini-2.5-flash"
+  api_key: your_gemini_api_key
+```
+
+## Development
+
+### Adding a New LLM Provider
+1. Add new model configuration in `conf.yaml`
+2. Implement corresponding API call logic
+3. Test connection and inference
+
+### Customizing Prompt Templates
+1. Create a prompt template file
+2. Reference the template in `conf.yaml`
+3. Test prompt effectiveness
