Me Here ffededd05b PM_K-1 CircuitPython: self-contained RGB LED + fix screen tearing ...

From on-board feedback (memory + colours now good):
  - LED: drive the WS2812 via the core neopixel_write module (no neopixel library to
    install) — a tiny RGB class. Self-contained: it works straight from the bundle.
  - Tearing: switch displayio to auto_refresh=False and push a complete frame only when
    the scene changed (dirty flag, capped at the panel's refresh rate) so updates are
    never shown mid-paint. Beat dots now recolour in place (vectorio color_index) instead
    of being rebuilt every beat, shrinking the dirty region.
