fix(cli): make the command-line client work on Windows

Its suite had only run on Linux. On Windows, against a real hub and node and
from the installed meshbay-cli.exe:

- secrets.enc was written in text mode (os.open without O_BINARY): every 0x0A
  of the ciphertext became CR LF and the saved session "does not open with
  its key" on the next run.
- isatty() is true for NUL, so a script run with `< NUL` or by the Task
  Scheduler was asked questions instead of told to pass --yes;
  output.terminal() checks for a real console.
- Ctrl+C waited for the selector loop's next timer, up to half a minute in
  `chat --follow`; the loop now points the signal wakeup at its self-pipe,
  as the proactor does.
- Right-click copy and paste raised: asyncio cannot start a process on the
  selector loop; the clipboard tool runs in a thread.
- Tab completion of remote paths ran on the default (proactor) loop, which
  never opens a node, and wrote in the locale encoding; the PowerShell script
  now reads it as UTF-8.
- `get -R` into a folder past MAX_PATH died with a traceback; get, put, the
  resume file and the interactive mode use the extended form at each disk
  call, as the node does.
- `groups` showed a SQLite hub's naive UTC time as local time.

The opt-in end-to-end suite now runs on Windows (16 tests: Chrome found under
Program Files and started with the real environment, VLC as the player, Ctrl+C
through a console of its own, PowerShell 5.1 completion of an accented name).
