remove legacy completions endpoint

[kalafus]

What

remove legacy completions endpoint (uses obsolete models and truncates responses)

Why

legacy .completions(query: CompletionsQuery) endpoint technically still works, but it frequently truncates responses. the .chats(query: ChatQuery) endpoint is available and not janky.

Affected Areas

.completions(query: CompletionsQuery)

Pull includes a deprecation message for the /v1/completions endpoint, which, some kind of deprecation message is probably technically the correct path at this time..
