feat(cmf): per-model reasoning switch — 'thoughts: off' for thinking models

Each Local-models row gains a thoughts selector (auto/off). Off injects
enable_thinking=false (cortiq >= 0.2.1 renders the chat template with an empty
<think> block) into requests that don't set it themselves — the model answers
directly, faster and shorter. A client-supplied enable_thinking always wins.
