* 'closed' is OUR OWN sfuUnsubscribe() — never rebuild on that
* (Chrome fires the state change synchronously before sfuSubPC is
* null'd, which used to trigger a subscribe→close→subscribe loop
* every time anyone deliberately tore down the sub).
* 'closed' coming from our OWN sfuUnsubscribe() must NOT rebuild
* (subscribe→close→subscribe loop). sfuUnsubscribe nulls
* sfuSubPC BEFORE pc.close(), so the `sfuSubPC === pc` guard
* catches self-teardown — the guard fails and we early-return.
* 'closed' coming from the SFU (server-side close — e.g. our
* own wedge-recovery in renegotiateLocked) DOES need a rebuild
* because sfuSubPC === pc is still true (we didn't tear down).
* Without this branch the host's sub stays at sub=none after
* any server-driven close, every subsequent track add goes
* nowhere. Fox 2026-06-04: "lost cohost camera / screen
* share" was downstream of this missing rebuild.
