KiCad - the KiCad Bridge

"""quiet_console.py — no console window may EVER blip onto the user's screen.

John (2026-08-15): "if you're doing a lot of powershell commands via your bridge
... when you open them, don't make a terminal window come to the foreground and
blip." Root cause: the bridge server runs WITHOUT a console (ab spawns it
CREATE_NO_WINDOW / Start-Process -WindowStyle Hidden), so every CONSOLE child it
launches (powershell.exe, kicad-cli.exe) makes Windows allocate a brand-new
VISIBLE console window — a foreground blip per call. GUI children (kicad.exe,
eeschema, pcbnew) are unaffected by the flag either way.

Fix, centrally: imported ONCE at server boot, this wraps subprocess.Popen (which
subprocess.run/check_output use internally) so CREATE_NO_WINDOW is OR'd into
creationflags by default on Windows. Every current and FUTURE subprocess in the
bridge inherits the fix — no per-call-site discipline required. Explicit
creationflags passed by a caller are preserved (we only OR the bit in).
