Subject: [PATCH] fix(agent): resolve thinking_level from model config by model
 ID or name

Fix cfg.GetModelConfig(model) at instance.go:160 to correctly resolve
thinking_level when model is a full model ID (e.g.
openrouter/qwen3.6-plus-preview:free) instead of a model_name
(e.g. openrouter).

GetModelConfig only matches by model_name, but lookupModelConfigByRef
handles both model_name and full model ID. This fixes the issue where
thinking_level was not being read from the config.

Fixes #2286
