feat(sdk): Python and JS SDKs for API v1.4.0

[Oanakiaja]

1.4.1

Bug Fixes

• Fix fnm environment variables not working in non-interactive shells:
  nodejs.sh was appended after the non-interactive early return in
  /etc/bash.bashrc, causing bash -c calls to fail to access node/npm paths. Now
  inserted at the top with a guard to prevent duplicate PATH entries.

1.4.0

Features

• Proxy Mapping: Replace TinyProxy with GOST v3, supporting proxy
  domain/IP/port mapping and HTTPS proxy mapping.
• Workspace: Unify WORKSPACE as the global sandbox working directory, used by all execution endpoints by default (shell/bash/code/jupyter/nodejs + VS Code + JupyterLab).
• Agent Browser: Optimize agent-browser experience with automatic CDP
  connection to in-container Chromium, supporting daemon connect mode.

Bug Fixes

• chown home directory after user creation to fix permission issues with
  volume mounts under the home directory.

1.4.1

Bug Fixes

• 修复 fnm 环境变量在非交互式 shell 中不生效的问题：nodejs.sh 原先被追加在
  /etc/bash.bashrc 非交互式提前返回之后，导致 bash -c 等调用无法获取 node/npm
  路径。现改为插入到文件顶部，并增加守卫防止 PATH 重复。

1.4.0

Features

• Proxy Mapping：替换 TinyProxy 为 GOST v3，支持 proxy 域名/IP/端口映射和
  HTTPS 代理映射。
• Workspace：统一 WORKSPACE
  作为全局沙箱工作目录，所有执行端点默认使用（shell/bash/code/jupyter/nodejs +
  VS Code + JupyterLab）。
• Agent Browser：优化 agent-browser 使用体验，自动通过 CDP 连接容器内
  Chromium，支持 daemon connect 模式。

Bug Fixes

• 用户创建后 chown home 目录，解决 volume mounts 到 home 目录下的权限问题。
