Ryan Malloy cd3a8cc6be Add SCO modulator, external audio input, and demo scripts ...

- sco_mod: 9-channel FM subcarrier oscillator modulator (inverse of sco_demod),
  with round-trip tests proving voltage recovery across all channels
- fm_voice_subcarrier_mod: add audio_input parameter to accept external float
  streams (e.g., Apollo mission voice recordings) instead of internal test tone
- loopback_demo.py: streaming TX->RX round-trip with CLI for noise/voice/frames
- agc_loopback_demo.py: full Virtual AGC integration via TCP bridge
