What changed from 0.2.2

• Recording from the FM-1 over USB works. In 0.2.1 and 0.2.2 a computer recording the FM-1's USB audio input got
  mostly silence (82-85 % zeros, 2-15 ms of sound every ~29 ms). felucca-bsp's stall check (the host stopped
  reading for over 20 ms) counted USB polls as if only its 2 kHz timer polled; RemoteFM1 also polls from its main
  loop, 100,000-225,000 times a second, so the stream was dropped every millisecond. It now counts milliseconds
  (felucca-bsp patch 0003, hook FELUCCA_USB_MS).
• Playing to the FM-1 over USB, Bluetooth, the screen and the protocol are unchanged.

Testing

On an FM-1 on 2026-10-28, with a Mac: a 1503 Hz tone played to the FM-1's USB audio output and recorded back from its
input. 0.2.2: 15 % of the samples sound, 234 gaps over 1 ms in 7 s. 0.2.3: continuous, no gap over 1 ms, every 20 ms
window a clean sine. A RemoteFM1 session (HELLO) over USB-MIDI answered as before.
