 * Main adapter plugin that is a common interface between AI features and AI adapters.
 *
 * Various AI features require to make calls to AI services. On the other hand, there are various AI adapters that can be
 * loaded, which provide access to different AI service providers.
 *
 * `AIAdapter` brings both parties together. Features use the `AIAdapter` API that is known to them. On the other hand, a concrete adapter
 * implementation can inject itself into `AIAdapter`. This way features and adapters are decoupled.
 *
 * For example:
 *
 * * `AIAssistant` feature needs to make text AI requests, so it uses `AIAdapter#textAdapter`.
 * * `OpenAITextAdapter` plugin, when loaded, sets itself as `AIAdapter#textAdapter`, so features can use it.
