tkpdx01 6074fdeb71 feat(cardputer-adv): add TCA8418 keyboard and WiFi config UI (#1929) 
Add full keyboard support and keyboard-based WiFi configuration for
M5Stack Cardputer Adv:

- TCA8418 I2C keyboard driver with 56-key matrix, interrupt-driven
  key events, and debounce handling
- Keyboard WiFi config UI: scan/select/input SSID and password
  directly on the device without needing a phone
- Volume control (up/down arrows) and brightness control (left/right)
  via keyboard with fine-step adjustment near bounds
- Enter key to toggle chat state
- Display offset and backlight fixes for ST7789V2
- README with flash parameters and hardware specs

烧录参数

芯片: ESP32-S3, Flash: 8MB, 模式: DIO, 频率: 80MHz

地址 文件
0x0 bootloader/bootloader.bin
0x8000 partition_table/partition-table.bin
0xd000 ota_data_initial.bin
0x20000 xiaozhi.bin
0x600000 generated_assets.bin

烧录命令 (build 目录为 build-cardputer-adv):

python -m esptool --chip esp32s3 -b 460800 -p PORT \
  --before default_reset --after hard_reset \
  write_flash --flash_mode dio --flash_size 8MB --flash_freq 80m \
