Me Here b419ad0daa Phase 1: CircuitPython firmware (USB-drive edition) for the Kit ...

New pico-cp/ — a CircuitPython port of the PM_K-1 firmware so the Pico mounts as a
CIRCUITPY drive carrying its code + tracks (the MicroPython pico/main.py stays the
simple fallback):
  - pico-cp/code.py: displayio BusDisplay driving ST7796 via a custom init_sequence;
    smooth anti-aliased text via displayio Bitmap+Palette (reuses the baked font blobs);
    vectorio rects for dots/buttons; DIY GT911 touch (16-bit regs, edge-detected);
    pwmio buzzer, analogio joystick, digitalio buttons, optional neopixel RGB; the
    polymeter engine on a time.monotonic_ns scheduler. Reads /programs.json (falls back
    to baked defaults); CircuitPython auto-reloads on file change.
  - pico-cp/programs.json: the 23 default grooves. pico-cp/README.md: flash + calibrate.
  - build.sh/deploy.sh: bundle + serve /pm_k1_circuitpy.zip. info-kit.html: experimental
    'CircuitPython edition — USB drive' section.

Verified in CPython (stubbed displayio): init sequence well-formed, parser handles the
grooves incl. (3,8) euclid + @-4 gain, and code.py's actual make_text renders identical
smooth AA text. Hardware bits (panel/touch/MIDI) await on-board testing.
