42 * Build the `system/init` SDKMessage — the first message on the SDK stream
43 * carrying session metadata (cwd, tools, model, commands, etc.) that remote
44 * clients use to render pickers and gate UI.
45 *
46 * Called from two paths that must produce identical shapes:
47 * - QueryEngine (spawn-bridge / print-mode / SDK) — yielded as the first
48 * stream message per query turn
49 * - useReplBridge (REPL Remote Control) — sent via writeSdkMessages() on
50 * bridge connect, since REPL uses query() directly and never hits the
51 * QueryEngine SDKMessage layer
