enricobuehler e44f2b1024 fix(gamestream): say "the app quit", not just goodbye
Disconnecting the ENet peer stopped the freeze but the client then reported the
session as error -1: a bare disconnect is indistinguishable from the host
falling over, so Moonlight called it a connection failure. Which, from its side,
was a fair reading — we never said otherwise.

The protocol has a word for this. Send the TERMINATION control message with
`NVST_DISCONN_SERVER_TERMINATED_CLOSED` first, then disconnect; the client maps
that to a graceful termination (given it has seen a frame, true of any real
session) and lands the player back in the app list.

Constants verified against moonlight-common-c `ControlStream.c` rather than
recalled, because every way of getting this wrong is silent — the client ignores
an unparseable control message, which reads on glass as the same freeze:

* the type comes from the table the CLIENT chose, so it is derived from the
  negotiated nonce scheme (plain 0x0100 / encrypted 0x0109) instead of guessed,
* the reason is BIG-endian (the >=6-byte branch; the short branch is a
  little-endian u16, which is GFE's older shape).

`disconnect_later` rather than `disconnect`, so the queued message actually
reaches the wire instead of racing the teardown — which would land us back at -1.

The session's GCM key is cached per tick because ending a session clears the
launch state the key lives in, and this is precisely the message that has to be
sealed after that.
