Install claude and opencode via bootstrap; drop nvm in favor of fnm

Cheap Savitech chip firmware stalls on rapid SET_INTERFACE / sample-rate
renegotiation, eventually dropping off the USB bus and requiring a
physical replug. Two fixes, both scoped to this exact device only:

- snd_usb_audio quirk_flags (262a:10aa): fixed_rate + ctl_msg_delay +
  iface_delay, applied via /etc/modprobe.d during bootstrap.
- WirePlumber: disable idle-suspend for the device's ALSA node so
  PipeWire doesn't repeatedly reopen the stream during normal use.
