Localize in Chinese

Once #5 is complete, localize the framework in Chinese.

Do not use AI to translate as these are often wrong leading to a poor experience. We want accurate and clear translation. Where possible, use a human with a high level of Chinese experience to translate and proofread. If that is not possible, use a localization service or a tool with a good track record for accurate translation backed by human proof-reading such as the Apple Translate app.
