Based on https://github.com/tslabs/zx-evo/tree/master/pentevo/esp32, extended with an SMB2/3 server that exposes the ZX Evolution's real SD card as a network share (browse/download/upload/delete), plus assorted stability and protocol-correctness fixes in vfs_bridge.cpp and the vendored libsmb2 - see firmware/README.md for the detailed changelog and current status. Also adds: - firmware/: ready-to-flash compiled binaries + flashing instructions - hardware/: adapter board connection diagram, PCB photo, and Gerber files - src/third_party/libsmb2: vendored from sahlberg/libsmb2 (LGPL-2.1, see its own COPYING/LICENCE files), de-submoduled to a plain snapshot with local patches applied directly Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
