Right now, AI modules and features are hardcoded in
`Configuration::Feature` and `Configuration::Module`. If another plugin
wants to register an AI-powered feature (with its own agent, LLM config,
and a spot on the AI features admin page), there's no way to do it
without modifying discourse-ai directly.
Data explorer needs a query generation agent, and other plugins will be
able to add their own agents too. So we need a proper extensible API
here.
The consumer code ends up looking like this:
```
DiscoursePluginRegistry.register_external_ai_feature(
{
module_name: :data_explorer,
feature: :query_generation,
agent_klass: DiscourseDataExplorer::AiQueryGenerator,
enabled_by_setting: "data_explorer_ai_queries_enabled",
},
self,
)
```
