Wrap Ollama native streams with the shared plain-text tool-call compatibility wrapper so local/plain-text tool requests are delivered as structured toolCall events when matching tools are available.
Verified with live local Ollama proof, focused Testbox Vitest, Testbox check:changed, and autoreview.
* fix(ollama): strip provider prefix from model ID in chat requests
buildOllamaChatRequest passed params.modelId directly to the Ollama API
without stripping the "ollama/" provider prefix. The embedding provider
already handles this (normalizeEmbeddingModel at line 100), but the chat
stream path did not. When setup writes the primary model as
"ollama/<model>" or the model ID flows through without normalization,
the Ollama API rejects it with a 404.
Closes#67435
