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 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+# Modern ESP-IDF (idf_component_register) wrapper around the vendored
+# libsmb2 checkout at E:\esp32\src\third_party\libsmb2 (upstream
+# sahlberg/libsmb2, LGPL-2.1). Vendored outside components/ deliberately:
+# ESP-IDF auto-scans every immediate subdirectory of components/ as a
+# candidate component, and libsmb2's own CMakeLists.txt predates
+# idf_component_register (calls add_definitions() at the top level, which
+# ESP-IDF 6.1's two-pass component requirement scan rejects with
+# "add_definitions command is not scriptable") — so it must never be
+# auto-discovered directly. Source list and compile definitions below are
+# copied from the upstream lib/CMakeLists.txt ESP_PLATFORM branch, minus
+# aes_apple.c/krb5-wrapper.c (excluded there too for this platform).
