* fix(t-watch-ultra): build with the esp32s3 flags, not the classic-ESP32 ones
The env was the only esp32s3 variant extending ${esp32_base.build_flags} (since
#8171). That base adds -D ESP32_FORCE_IRAM_MEMSET -Wl,--wrap=memset
-Wl,--wrap=memcpy, and the wrappers in IramMemcpy.c/IramMemset.c decide whether
the cache is on by reading 0x3FF00040 - DPORT_PRO_CACHE_CTRL_REG on the classic
ESP32, an address the S3 does not map at all (soc.h: DRAM 0x3FC88000-0x3FD00000,
DROM 0x3C000000-0x3E000000, IRAM 0x40370000-0x403E0000, peripherals 0x60000000).
--wrap is link-wide, so every memcpy/memset in the image - including inside the
precompiled WiFi, lwIP and flash driver libraries - branched on that undefined
read. Two long-standing board-specific bugs came from it, both dating to #8171,
which introduced the wrong base and the first workaround in the same commit:
* WPA2 networks associated and completed the 4-way handshake, then never got a
DHCP lease, while open networks worked normally (#11513).
* Direct flash reads returned 0x00 for data that was correct on flash, so NVS
came up empty every boot and dropped BLE bonds (#11530).
Switching the env to esp32s3_base fixes both on hardware: WPA2 gets a lease, and
NVS survives a reboot with the bond intact. The read workaround that #11530
needed - -Wl,--wrap=esp_partition_read, -Wl,--wrap=esp_flash_read and
esp_partition_read_mmap_wrap.c - is therefore removed as well.
The module excludes the env inherited from esp32_base go with it, so the board
now matches every other esp32s3 variant: web server and paxcounter are built
(paxcounter still only runs when enabled in config), and MESHTASTIC_EXCLUDE_AUDIO
was already inert here because AudioModule additionally requires USE_SX1280.
-UMESHTASTIC_EXCLUDE_ACCELEROMETER goes too, having only existed to undo an
inherited -D.
Also guards ESP32_FORCE_IRAM_MEMSET behind CONFIG_IDF_TARGET_ESP32, so a variant
cannot enable the classic-ESP32 probe on another target again.
* Update platformio.ini
added missing ${device-ui_base.custom_sdkconfig}

Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
