Update FreeRTOS configuration and enhance upper computer AI documentation

- Increased total heap size in FreeRTOSConfig.h from 10000 to 18000.
- Modified stack sizes for various tasks in freertos.c to improve performance:
  - initTask: 128 to 256
  - CarCtrlTask: 256 to 1024
  - timerTask: 512 to 1024
  - sr04Task: 128 to 512
  - rc522Task: 128 to 512
- Added comprehensive upper computer AI guide for TCP client implementation, detailing protocol contracts, command sets, telemetry, architecture requirements, and error handling strategies.
- Introduced a Python web upper computer AI guide with a recommended tech stack and project structure.
- Created a Chinese version of the upper computer AI guide for local developers.
- Updated STM32 project configuration to reflect new task stack sizes and heap settings.
- Adjusted configuration files for various tools to ensure compatibility with the new project structure.
