Description
**Describe the problem you have/What new integration you would like**
The daly bms component in esphome is missing the important battery failure status at address 0x98.
[Daly-UART_485-Communications-Protocol-V1.21-1.pdf](https://github.com/user-attachments/files/16463852/Daly-UART_485-Communications-Protocol-V1.21-1.pdf)
**Please describe your use case for this integration and alternatives you've tried:**
I'd really like to know why the bms has tripped is MOSFETs in cases like cell voltage protection.

Research direction
Start by reading the linked Daly-UART_485-Communications-Protocol-V1.21-1.pdf, focusing on the battery failure status at address 0x98, then locate the ESPHome Daly BMS component. Done means the component exposes this status so users can determine why the BMS tripped its MOSFETs, including cases such as cell voltage protection.
