/**
 * Shared message type shapes for the OpenCode plugin API's `messages` array.
 *
 * These types describe the structure of chat messages passed through
 * `experimental.chat.messages.transform` and related hooks. All fields
 * are unioned across the files that previously defined them privately —
 * optional extras are harmless under structural typing.
