CydandClaude Fable 5 4391ddd322 restoration: import PlasmaNew — the plasma display replica effort ...

Moved from the vRIO repository to live with the other hardware
restoration work. Contains the PD01D221 reverse-engineering reference
(FIRMWARE.md, recovered from the TMS27PC512 EPROM dump) and the working
Matrix Portal S3 + HUB75 replica firmware (flashed and bench-tested
2026-07-22, including the G/B pin swap for these panels, the
PIN_BUTTON_UP/DOWN fix, and power-on cursor rendering).

The vPLASMA reference oracle (src/VPlasma.Core) and the VPlasma.Wire
differential-test tool stay in the vRIO repo; PlasmaNew pre-move commit
history is there too.
