/**
 * Streaming dispatch gate. Its only job is to control EMISSION per dispatch mode
 * and surface the model's own control tool — it does NOT consult the host guard.
 * The guard has a single owner (`hostLoop`): when this returns empty text and no
 * control, `hostLoop` runs the guard exactly once. Keeping the guard out of here
 * avoids double-evaluation and keeps guard telemetry attributable.
 *
 * - relaxed: stream live; if the model's own control tool fires, cancel any
 *   streamed text and return that control.
 * - strict: emit NOTHING until the model's intent is known — buffer until the
 *   first substantive token (answering → flush + stream the rest live) or source
 *   end (no answer → return empty; `hostLoop` then guards with no leak).
