Research direction

Reproduce the parser behavior with the documented list<string|MessagePart|array> example and trace how generic types are split. Verify that the complete generic remains one type, that its inner union is preserved, and that aliases inside it can still be resolved.

Written by the indexing model from the issue text.

Description

Given:

@param list<string|MessagePart|array> $prompt

the parser returns three types:

\list<string
\MessagePart
\array>

Expected: list<string|MessagePart|array> remains one type, with aliases resolved inside the generic if applicable.

This is part of an issue with wp_ai_client_prompt() documentation.
