docs: Add type annotations to navigate.js

[Lang-Qiu]

问题背景

This PR addresses the lack of type annotations in the navigate.js file, which can reduce code readability and maintainability. Adding type annotations helps developers understand the function's expected inputs and outputs, improving overall code quality and supporting tooling like IDEs.

修改内容

• Added JSDoc type annotations to the exported default function in src/main_world/navigate.js.
• The annotations include a @param tag for location as a string and a @returns tag indicating void.
• This change enhances documentation without altering the function's behavior, making it easier for contributors to work with the codebase.

验证方式

• Verified that existing tests pass without any changes, confirming no functional impact.
• Manually checked that the annotations are correct and consistent with the function's implementation.
• No new tests were added as this is a documentation-only change.

其他信息

• No breaking changes introduced.
• No need to update external documentation since the annotations serve as inline documentation.
• No known limitations.
