fix(prompts): clarify language detection rules for edge cases (#11696)

* fix(prompts): clarify language detection rules for edge cases

Update LANG_DETECT_PROMPT to explicitly handle cases where the input text describes a language but is written in a different language. Add examples to illustrate the expected behavior.

* fix(prompts): correct language code mapping for Chinese input

Update the language detection prompt to properly map '英语' to 'zh-cn' instead of 'en-us' since it's a Chinese word

It is crucial to focus strictly on the language *of the input text itself*, and not on any language the text might be referencing or describing.
- **Crucially, if the input is 'Chinese', the output MUST be 'en-us', because 'Chinese' is an English word, despite referring to the Chinese language.**
- Similarly, if the input is '英语', the output should be 'zh-cn', as '英语' is a Chinese word.
