Lingma streams answers via chat/answer + chat/finish notifications and
never sends a JSON-RPC response for chat/ask. The old code awaited
rpc.request("chat/ask") and swallowed the TimeoutError, so every chat
was forced to wait the full rpc_timeout (default 30s) before draining
the stream queue - even though the first token was already present in
the queue within ~2s.
Effect:
- non-stream TTFB dropped from ~30s to actual upstream latency (~2-3s).
- stream first-chunk dropped from ~30s to upstream first-token latency.
- consume_stream idle timeout decoupled from rpc_timeout so shortening
rpc_timeout no longer starves long completions.
Switch chat/ask to rpc.notify (fire-and-forget) and rely entirely on the
existing chat/answer + chat/finish handlers for result delivery.
