Actors v2 Stage 1: Payloads, Guards, and the Wire That Was Already There
Actors v2 Stage 1 lands on unstable. Payload-bearing message variants compile end-to-end. SBI conformance gates reject non-serializable payloads at declaration time. Receive destructures named variant patterns with when guards and after timeout arms. SPEC-029 send safety integrates with ActorRef sends. Plus the WASI/browser carrier merge and a zb throttle fix.
