  "message": "Move SUBSCRIBE to a dedicated bidirectional stream.\n\nThis change refactors MoQT to handle SUBSCRIBE messages on their own bidirectional streams, rather than on the control stream.\n\nKey changes include:\n-   New `MoqtSubscribeRequestStream` and `MoqtSubscribeResponseStream` classes.\n-   `MoqtSession::Subscribe` now opens a bidi stream and sends the SUBSCRIBE message on it.\n-   `MoqtSession::Unsubscribe` now resets the bidi stream associated with the subscription.\n-   `MoqtSession::RequestUpdate` sends the update on the existing subscribe bidi stream.\n-   The control stream no longer processes SUBSCRIBE, SUBSCRIBE_OK, or UNSUBSCRIBE messages.\n-   `MoqtUnsubscribe` message type and serialization/parsing are removed.\n-   MoqtSession no longer owns any subscriptions\n-   All external state is now destroyed in Detach(). On teardown, streams are destroyed in arbitrary order, making clearing such state in the destructor dangerous.\n\nI wrote better helper functions in MoqtSessionTest to reduce the toil in sending/receiving messages, setting up bidi streams, and not hard-coding message formats.\n\nPiperOrigin-RevId: 949593252\n",
