Ollama doesnt work in a graalvm native image

[joshlong]

for my trivial example, I had to register a RuntimeHintsRegistrar with the following types:

 // ollama
            for (var c : new Class[]{ThinkOption.ThinkOptionDeserializer.class,
                    ThinkOption.ThinkOptionSerializer.class}) {
                hints.reflection().registerType(c, MemberCategory.values());
            }

Hi, I can take a look at this.

The issue seems to be that ThinkOption uses custom Jackson serializer/deserializer classes, while OllamaRuntimeHints currently only registers the JSON-annotated Ollama types discovered by package scanning. The using = ... serializer/deserializer classes are not registered by that scan, so adding explicit reflection hints for ThinkOption.ThinkOptionSerializer and ThinkOption.ThinkOptionDeserializer should keep the fix focused.

I can work on a small PR with a focused runtime hints test. Please let me know if you prefer a different direction.

@DragonFSKY Feel free to submit a PR, I will review it.
