temphummon dev ebbeffa432 Add bit-probe results, decimal point/percentage bit map, and working temperature+humidity display
- bitprobe.c: interactive single-bit probe that discovered the display glyph
  layout and the decimal point / percent sign bit positions
- temphummon.c: render top line '188.8°C' and bottom '88.8%' using the
  verified decimal points (f[4], f[8] bit5) and percent sign (f[10] bit5)
- PROJECT_MEMORY.md: document full frame layout + empirical bit map
- README: add wiring table and project memory pointer
- add Waveshare reference zip and flake.lock
