/**
 * Build `gen_ai.input.messages` / `gen_ai.output.messages` payloads.

 * The Weave Agents extractor mines `text` and `reasoning` parts for chat content
 * and renders tool cards from `execute_tool` SPANS (not from tool_call message
 * parts) — so we keep messages focused on assistant content and let the tool
 * spans carry arguments/results. Shapes follow the Weave SDK MessagePart union.
