Add LeRobot Dataset Tools Wiki, Improve LeRobot Wiki Structure, and Add English Documentation

[Miscanthus40076]

增加了lerobot各种策略的wiki本 PR 主要完善了 LeRobot SO100/SO101 机械臂中文 Wiki 中「策略训练/评估、进阶训练与数据集工具」等内容。

变更概览

• 完善 docs/zh-CN/Robotics/Robot_Kits/Lerobot/cn_Lerobot_SO100Arm_New.md：
  • 将策略相关内容补齐并按策略分块组织（<details> 折叠块）。
  • 在策略教程后补充进阶内容，并同样使用折叠块收纳：
    • （可选）使用 🤗 PEFT 进行高效微调：提供安装方式、lerobot-train 示例与关键参数说明（LoRA / --peft.*）。
    • （可选）在训练时使用多 GPU（Accelerate）：给出命令行启动方式、accelerate config 可选流程，以及多 GPU 下步数/学习率的常见调整建议。
  • 增加并整理录制过程中的操作提示与工程化建议：
    • 键盘方向键的使用逻辑与“丢弃低质量剧集”的实践建议。
    • 摄像头连接注意事项（不建议多个摄像头共用同一 USB HUB；优先 USB3.0 直连）。
    • 舵机校准前/后的注意事项（区分 SO101 Leader/Follower 编号与减速比；校准时驱动板单独连接 6 号舵机等）。
  • 增加故障处理流程：当出现 Magnitude ... exceeds 2047 报错时，提供使用 Seeed SoARM 快捷工具进行**中位校准（2048）**的步骤说明，并引导回到整臂校准流程。
  • 将检查 CUDA 可用性的 Python 片段改为可直接在 bash 中执行的 python - <<'PY' ... PY 写法，减少复制粘贴出错概率。
  • 修复一个会触发 MDX 编译失败的空链接（[数据集工具]()）为有效的相对链接（[数据集工具](./数据集工具.md)）。

新增文档

• 新增 docs/zh-CN/Robotics/Robot_Kits/Lerobot/数据集工具.md：
  • 介绍 lerobot-edit-dataset 的常用操作与示例命令，包括：删除剧集、拆分/合并、移除特征、图像转视频、上传到 Hub、在线/离线可视化等。

Add Wiki for LeRobot Strategies and Improve Chinese Wiki for SO100/SO101 Arms

PR Description:
This PR adds comprehensive wiki content for various LeRobot strategies and significantly improves the Chinese Wiki for the LeRobot SO100/SO101 robotic arms, focusing on strategy training/evaluation, advanced training, and dataset tools.

Change Overview

Updates to
docs/zh-CN/Robotics/Robot_Kits/Lerobot/cn_Lerobot_SO100Arm_New.md:

Completed missing strategy-related content and reorganized it by strategy type, using

Details

collapsible blocks for structured browsing.

Added advanced training sections after the strategy tutorials, also organized with collapsible blocks:

(Optional) Efficient fine-tuning with 🤗 PEFT
Includes installation instructions, lerobot-train examples, and key parameter explanations (LoRA / --peft.*).

(Optional) Multi-GPU training with Accelerate
Provides CLI launch examples, optional accelerate config workflow, and common adjustment guidelines for steps and learning rates in multi-GPU setups.

Added and refined operational and engineering best-practice notes for the data recording process:

Keyboard arrow key control logic and practical guidance on discarding low-quality episodes.

Camera connection guidelines (avoid sharing a single USB hub across multiple cameras; prefer direct USB 3.0 connections).

Servo calibration notes before/after calibration (distinguishing SO101 Leader/Follower IDs and gear ratios; calibration procedure requiring the driver board to be connected only to servo #6, etc.).

Added a fault-handling workflow:

For the Magnitude ... exceeds 2047 error, documented the procedure to use the Seeed SoARM quick tool for center calibration (2048), and guided users back to the full-arm calibration process.

Replaced the CUDA availability Python snippet with a bash-executable form:
python - <<'PY' ... PY, reducing copy–paste errors.

Fixed an empty MDX link that caused build failures:
数据集工具 → 数据集工具.

New Documentation

Added
docs/zh-CN/Robotics/Robot_Kits/Lerobot/数据集工具.md:

Introduces common operations and example commands for lerobot-edit-dataset, including:

Episode deletion

Dataset split/merge

Feature removal

Image-to-video conversion

Uploading to Hub

Online/offline visualization

Additional Notes

All the above content has been translated into English.

The English documentation has been updated in sync with these changes.
