consider using find-bufo semantic search for custom tab

[zzstoatzz]

the custom tab currently searches custom emojis by filename only. we could potentially use the new find-bufo semantic search API for much better search results - it does cross-modal search with hybrid vector + BM25 search.

benefits:

• semantic search ("chilly bufo" would find winter/cold themed bufos)
• better than just filename matching
• already deployed and working

potential issue:

• custom tab may contain non-bufo GIFs
• find-bufo API only knows about bufos from bufo.zone
• would need to handle cases where custom emoji isn't in the bufo index

api:

POST https://find-bufo.fly.dev/api/search
{
  "query": "chilly",
  "top_k": 10
}

returns results with similarity scores. could fall back to filename search if no good matches found, or only use it for bufos.
