LAN7800 EEPROM Programmer - install.sh

by adom

MPLAB-Connect-parity EEPROM tool for the Microchip LAN7800 USB-3.1 to Gigabit-Ethernet controller (VID 0x0424 / PID 0x7800). Read an adapter's EEPROM to a .bin, edit MAC / VID / PID / bcdDevice / strings / serial and LED/GPIO with a byte-exact preview, and program hardware with verify-after-write. Reads are free; physical writes are gated behind --force-physical-write. Ships an AI-oriented CLI (single source of truth) plus a Hydrogen webapp that shells out to it.

# The CLI (cli/lan7800prog) needs its cli/lan7800/ package dir alongside it and
# the webapp finds the CLI relatively, so we install wrappers that point back
# into this module dir rather than copying files out of it.
