feat(config): add ext-deps alias for extension-dependencies configuration

- Added support for `ext-deps` as equivalent shorthand name for `extension-dependencies`
- Implemented validation to prevent using both config names simultaneously
- Updated documentation to reflect the new alias and usage restrictions
- Added test cases to verify ext-deps alias parsing works correctly
- Added test cases to ensure configuration error occurs when both names are used
- Refactored Translator.php to handle both configuration key variants
- Maintained backward compatibility with existing extension-dependencies usage

+`ext-deps` 是等价的简写名称。一个项目中只能使用其中一个配置名；同时出现 `extension-dependencies` 和 `ext-deps` 会产生配置错误。
+
 编译器会为每一项生成 `ZEND_MOD_REQUIRED`。Zend 在加载 TypePHP 模块时检查这些扩展是否已加载。该配置不表示原生链接库；C/C++ 链接依赖仍使用 `link-libs`。
