Function: classesAtOrBelow()
classesAtOrBelow(
cls): ("chat-thinking"|"chat-balanced"|"chat-fast"|"embedding")[]
Classes at or below cls in chat capability: the class itself plus every
less-capable chat band, in CHAT_CLASS_ORDER. Treats a chat cls as a
ceiling - requesting ModelClass.ChatBalanced yields
[ChatBalanced, ChatFast], never ModelClass.ChatThinking - so a
class ask can degrade downward to a smaller chat model but never escalate to
a larger one.
ModelClass.Embedding is its own modality, not a rung on the chat
ladder, so it yields just [Embedding]. An unrecognized class yields the
full chat ladder.
