Ollama thinking-capable models default to think=true when the parameter
is absent. When OpenClaw has thinking set to off, the request never
included think=false, so models continued generating thinking tokens
that were then discarded by the response parser, producing empty
responses.
Wire onPayload into the Ollama stream path so payload wrappers can
mutate the request body, and add an Ollama-specific wrapper that sets
top-level think=false when thinkingLevel is off.

The Ollama stream function requested `stream: true` from the API but
accumulated all content chunks internally, emitting only a single `done`
event at the end. This prevented downstream consumers (block streaming
pipeline, typing indicators, draft stream) from receiving incremental
text updates during generation.
Emit the full `start → text_start → text_delta* → text_end → done`
event sequence matching the AssistantMessageEvent contract used by
Anthropic, OpenAI, and Google providers. Each `text_delta` carries both
the incremental `delta` and an accumulated `partial` snapshot.
Tool-call-only responses (no text content) continue to emit only the
`done` event, preserving backward compatibility.
