Position analysis.
Lichess maintains a database of cloud engine evaluations for positions it
has already analyzed (mostly openings, around 320 million positions).
LichessApi::get_cloud_evaluation looks one up by FEN and returns its
principal variations if present, or an error if the position hasn’t been
evaluated. This endpoint is public and needs no bearer token; it’s meant
for occasional lookups, not bulk fetching — for that, use the exported
evaluation database from lichess.org directly.
