AI Assistant: Investigate transformations from inline extension

Prompts such as "Turn list into a table" do not work on a block-extension perspective as it would be necessary to transform the block into another one. Transforming into the AI Assistant block works, but user-provided prompts make it impossible to know beforehand that a transformation is necessary.
Let's look for a way to detect an intended transformation and how it can be carried out.

Start by comparing how prompts are handled in the inline extension and the block-extension perspective, focusing on cases such as “Turn list into a table.” Determine how an intended transformation could be detected and carried out, then verify that user-provided prompts can trigger the appropriate block transformation without prior classification.
