zooqueen 861db0f621 a request nobody hears is not a quorum problem, and a secret needs a way in
Two halves of opening a secret were missing, and both showed up the first time
this ran against the real ring rather than an in-process one.

The request reached no party. Parties subscribed to "mpc.reveal_request.*" and
the requester published to "mpc.reveal_request.<session>". This transport
delivers by exact map lookup on the topic — it has no wildcards — so the
subscription matched nothing, every node stayed silent, and the opening failed
as "0 of 2 answered" with all three shares present and nobody having been asked.
That reads like a quorum fault and is a routing one. Both sides name one literal
now; the session rides in the body, where a reader wants it anyway. The pattern
came from the NATS-era topics next door, where wildcards do work.

And nothing could seal. mpcrek requires a sealed root to bring and no tool in
the estate produced one, so the protocol had no beginning. reveal.Seal takes the
published group key and a secret — no share, no node, no round, because writing
to the committee needs none of that — and `mpcd seal` is that from a shell, with
the secret on stdin so it never becomes an argument other processes can read.

Sealing to the identity is refused. It decodes as a valid point, so the decoder
lets it through, and every answer verifies against it: a secret sealed there is
readable by anyone. A test asked for that and the first version did not do it.
