fix: 将MCU型号从STM32F103RCT6修正为STM32F103R8T6

- 修改ioc文件中的芯片型号配置
- 调整HeapSize从10KB减至4KB以适应20KB RAM限制
- 更新项目技术实现文档中的MCU规格和内存配置
- 更新MDK-ARM工程文件的芯片定义(STM32F103xB)
- 添加新的启动文件startup_stm32f103xb.s

+;*                      This module performs:

+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Configure the clock system
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M3 processor is in Thread mode,
