alexandClaude Sonnet 5 6d835bc44c Initial import: ESP32 ZiFi32 firmware with SMB2/3 VFS bridge

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

--- 1. Enable SPI
sudo nano /boot/firmware/config.txt

Add or uncomment:
dtparam=spi=on

sudo reboot

ls -l /dev/spidev*


--- 2. Connect ESP-SPI

For ESP32-S3:

MOSI    GPIO13
MISO    GPIO11
SCLK    GPIO12
CS      GPIO10

For ESP32-P4:
MOSI    GPIO20
MISO    GPIO22
SCLK    GPIO21
CS      GPIO23

RPi:
MOSI = GPIO10 (pin 19)
MISO = GPIO9  (pin 21)
SCLK = GPIO11 (pin 23)
CS0  = GPIO8  (pin 24)
CS1  = GPIO7  (pin 26)
