fix: align legacy "oh" naming with clawteam branding

[shadowinlife]

概述

项目从 oh / OpenHarness 更名为 ClawTeam 后，代码库中仍有大量残留的旧名称出现在 CLI 帮助文本、错误提示、文档和环境变量中。本 PR 统一清理这些遗留命名，同时保持对旧环境变量的向后兼容。

变更内容

代码修复（8 文件）：

• cli/commands.py — CLI docstring、用户提示中的 oh → clawteam
• harness/phases.py — 审批门控提示 oh harness approve → clawteam harness approve
• spawn/prompt.py — docstring 更新
• spawn/tmux_backend.py — docstring 会话命名 + 错误信息
• spawn/wsh_backend.py — 错误信息
• identity.py — OH_PLAN_MODE_REQUIRED 迁移为 CLAWTEAM_PLAN_MODE_REQUIRED（主）+ OH_PLAN_MODE_REQUIRED（回退）；_env() 参数名泛化
• events/hooks.py — shell handler 同时导出 CLAWTEAM_{key} 和 OH_{key} 环境变量

文档修复（6 文件）：

• README.md / README_CN.md / README_KR.md — 所有命令示例 oh → clawteam
• skills/clawteam/SKILL.md（×2）— 触发关键词标注为 legacy alias
• skills/clawteam/references/cli-reference.md（×2）— 默认路径 ~/.oh → ~/.clawteam

向后兼容

环境变量	策略
OH_PLAN_MODE_REQUIRED	保留读取（作为 fallback）+ 继续导出
OH_{event_field} (hooks)	继续导出，同时新增 CLAWTEAM_ 前缀版本
OH_MSG_* (watcher)	未改动 — 内部消息传递合约，不属于本次范围

@tjb-tech 请review这个patch, 我在使用中遇到了doc文档和安装后行为不一样的问题. 当前patch主要是针对从open harness到独立命令工具进行修正

@tjb-tech Yes, please! :) This is a critical PR, I want to "pull" it, but I can't due to the fear that everything might break.
