The Qwen3 template nests context_size, f16, and mmap under parameters,
where the typed model configuration ignores them. Move these options to
the root and correct three model-specific context overrides.
Test the real gallery data and generated qwen3-vl-4b-thinking YAML.
Document manual repair because template updates do not rewrite installed
configurations.
Fixes#12528
