/**
 * Renders a `ThinkingItem` (CHAT-006, V2-053).
 *
 * Live stream: while the model is still reasoning (`item.streaming`), the body
 * is always shown so the user sees live progress — regardless of the global
 * thinking toggle (Ctrl+T). After the block is finalized, the body follows the
 * global Ctrl+T toggle (or a per-block override from clicking the header).
 *
 * Placement: thinking rows always precede the ◆ Response / tool cards for
 * the same model step (agent emits thinking-block before assistant-message
 * and tool-call). Violet accent distinguishes reasoning from green replies.
