test(node): run the connection processes on Windows, source and frozen

Connection processes and the larger UDP receive buffer were written and
measured on Linux; nothing had run on Windows, and `meshbay-node.exe
webrtc-worker` had never run from a frozen build on any system.

- test_connection_processes.py failed on Windows (8 tests): the selector
  loop the suite uses there cannot start a process. A test marked
  `daemon_loop` now runs on the daemon's own loop, chosen through
  pytest-asyncio's loop factories.
- The build starts both frozen executables as connection processes and
  carries a connection through each (smoke-connection-process.py). The
  daemon's own smoke test never signs in to a hub, which is when the
  processes start.
- The warning for a receive buffer below what was asked named
  net.core.rmem_max on every system; it names it on Linux only. Windows
  grants the 4 MB.

Measured on an installed build in service mode, docs/WINDOWS-PORT.md §5.12:
two processes at startup and on a live change, a browser's handshake, chat,
a 200 MB download over 8 connections across both processes, an upload, a
video stream, and stop, restart and start leaving no process behind.
