Merge origin/main at b805e6154 into wt/toyos-netring

issues: every path that moves a handle refuses a stream's, a refused datagram is never Ok, and the track cites no implementation

Merge origin/main at 1d5325376 into wt/toyos-netring

issues: send_handles is refused by its type, a datagram's pending error wakes every sleeper, and a sender waits at a full queue

issues: the datagram room model holds a record at a full queue, and a nonblocking send at a full ring answers WouldBlock

issues: a held send ring is looked at again when a datagram leaves the queue or is dropped
