Per-model params.thinking in agents.defaults.models["provider/model"].params.thinking is accepted by the config schema but never consulted during thinking-level resolution. The global thinkingDefault always takes precedence.

Reproduction:
Set thinkingDefault: low globally, and params.thinking: high on a specific model. session_status shows Think: low regardless.

Root cause:
resolveThinkingDefault() checks cfg.agents.defaults.thinkingDefault first and returns immediately — never looks at per-model params. Per-model params ARE loaded via resolveExtraParams() but thinking is ignored by createStreamFnWithExtraParams().

Fix location:
resolveThinkingDefault() in model-selection module. Add per-model params.thinking check before global thinkingDefault fallback.

Workaround: Set thinkingDefault globally to desired level, or use /thinking per-session.
