Two compounding bugs that cause WebUI to discard or misrender agent
responses when using GLM models on Ollama Cloud:
1. _is_ollama_glm_backend() matched "ollama" in base URL, which
included Ollama Cloud (ollama.com). The hosted service correctly
reports finish_reason and is not affected by the local Ollama
stop-reason bug. Exclude "ollama.com" before the substring check.
2. _handle_session_chat_stream() hardcoded "partial": False in the
assistant.completed SSE event instead of reading result.get("partial").
The WebUI could not detect truncation and rendered partial responses
incorrectly (showing only the continuation instead of the full text).
Read the partial flag from the agent result, matching the pattern
used by other SSE paths in the same file.
