/minesweeper — a wine session streamed to the browser over RFB

a websocket byte relay onto x11vnc's tcp socket, the same shape as the
terminal's relay onto the pty sidecar. this is the piece plugins/desktop
could not have: a plugin cannot claim a websocket provider.

the rfb client is ours rather than vendored novnc — raw and copyrect,
one pixel format we dictate so a rectangle memcpys into ImageData. we
control the server, so the other eight encodings are surface we would
carry and never run.

execution, so owner-only: wine runs as the owner, which makes the game's
menus file dialogs over the owner's home.

two bugs worth keeping. the token key is BEARER_TOKEN, not token, so the
upgrade 401'd before any rfb byte moved. and the /status health check
opened a tcp connection to prove liveness — libvncserver blocks its
accept loop peeking for a websocket handshake, so a polled health check
filled the backlog and locked out the real viewer. a liveness check must
not be indistinguishable from a client; it reads /proc/net/tcp now.
