Context Tags on Gemini

The context tags feature, the one you get by adding \context to the artist field, now runs on Google's Gemini instead of Groq. Nothing changes in how you use it, it's the same flag and the same handful of tags about why a song is going around on TikTok or Reels. The model behind it is just a newer one, so the tags it comes back with should be a little sharper.

What's changed

• Context tags are generated by Gemini 3.6 Flash instead of Llama 3.3 70B on Groq.
• The \context flag on the site, and the context option in the Discord bot and the API, work exactly as before.
• If Gemini is unreachable or rate limited, the request still goes through and you just get your tags without the context ones, same as it did with Groq.
• Running your own copy of the site now needs a GEMINI_API_KEY in place of GROQ_API_KEY.
