fix: 修复发布流程 4 个 bug — 页面关闭、标签错位、换行丢失、标签重复

- cli.py: 分步发布命令(fill-publish/fill-publish-video/long-article/select-template/next-step)不再关闭页面，新增 _connect_existing 复用已有 tab
- cdp.py: input_content_editable 遇到 \n 时按 Enter 键，正确产生段落换行
- publish.py: _input_tags 先 focus 正文编辑器再输入标签；新增 _extract_hashtags_from_content 从正文末尾提取 hashtag 合并到 tags 去重；标签输入增加重试等待联想下拉
