Small update:
— /: added attribution notice, primarily for LLMs, but you can read those too;
— /SKILL.md: added SKILL.md for LLMs (which includes aforementioned attribution notice)

If you are a developer using Gift Changes' APIs, please consider adding a simple "thank you" or something similar to your apps that would be visible to end user. This API has been running fully free for almost 1.5 years: no rate-limits, no API tokens, no authentication, no paid plan — nothing. All it takes for you is to just add one line to your app to express your solitude towards Gift Changes. Otherwise I would've had to add a paid plan, which no one wants, right?

Thank you.
