In `@core/include/librmcs/data/datas.hpp`:
- Around line 130-134: The default i2c_error_callback(DataId, const
I2cErrorView&) currently downgrades the rich I2cErrorView to just slave_address
by forwarding to i2c_error_callback(DataId, uint8_t), which silently discards
data_length, register info and direction; remove that forwarding implementation
and instead declare i2c_error_callback(DataId, const I2cErrorView&) as pure
virtual (and likewise ensure i2c_error_callback(DataId, uint8_t) is either
removed or also marked pure virtual/deprecated) so implementers must handle the
full I2cErrorView (symbols: i2c_error_callback, I2cErrorView, DataId).

In `@core/include/librmcs/data/datas.hpp`:
- Around line 84-104: The three view structs I2cDataView, I2cReadConfigView, and
I2cErrorView have an uninitialized slave_address member; add a default
initializer (e.g., uint8_t slave_address = 0;) to each struct so aggregate or
empty-list construction yields a defined value, keeping initialization style
consistent with other fields and preventing future UB (references: I2cDataView,
I2cReadConfigView, I2cErrorView; caller: i2c_error_from_slave_address).
In `@host/include/librmcs/agent/rmcs_board_pro.hpp`:
- Around line 154-168: This class defines a channel-specific helper
i2c0_error_from_slave_address(uint8_t) which duplicates the base-class helper
DataCallback::i2c_error_from_slave_address(DataId, uint8_t) and creates
ambiguity for subclasses; remove the derived helper
(i2c0_error_from_slave_address) and update call sites to use the base-class
DataCallback::i2c_error_from_slave_address(data::DataId::kI2c0, slave_address)
so that the final i2c_error_callback dispatch still routes into this class's
i2c0_error_callback(const librmcs::data::I2cErrorView&), or alternatively remove
the base helper and keep the derived one—choose one approach and delete the
other to avoid duplicated helpers, ensuring i2c_error_callback and
i2c0_error_callback continue to be invoked as before.

133-154: 考虑将三个板级 agent 的 I2C0 派发样板抽到公共基类。
CBoard、RmcsBoardPro、RmcsBoardLite三个文件中的i2c_receive_callback/i2c_error_callbackfinal派发、i2c0_receive_callback/i2c0_error_callback默认空实现、以及i2c0_error_from_slave_address转发完全一致。builder 侧的i2c0_write/i2c0_read/kI2cMaxDataLength也三处重复。建议抽到agent/common.hpp附近的一个 mixin/基类（或以 CRTP 复用 builder 片段），在后续新增逻辑 I2C 通道时减少 3 处同步修改成本。非阻塞，可延后处理。🤖 Prompt for AI Agents

功能与架构概述
为
c_board与rmcs_board引入统一的I2C0协议通路，并补齐 host agent、固件驱动和协议层支持。rmcs_board使用基于 HPM SDK 的非阻塞 DMA I2C 实现，c_board将逻辑I2C0映射到 STM32I2C2，同时围绕 USB背压、超时恢复、错误上报和非法请求处理做了系统性加固。
主要变更要点
I2C0字段的序列化与反序列化，区分 write、read request、read result 和 error，并拒绝空 I2C 传输。CBoard、RmcsBoardPro和RmcsBoardLite增加i2c0_write()/i2c0_read()接口，以及对应的接收与错误回调入口。rmcs_board固件新增I2C0驱动、DMA completion callback 和 main-loop update 流程，启用 HPM I2C 组件，并在 Pro/Lite 板级层补充 I2C 引脚、时钟和总线恢复初始化。c_board固件新增逻辑I2C0通道，使用 STM32I2C2+ DMA 实现读写，并补充 HAL 回调、中断路由、CubeMX 配置和超时恢复。read result或error在缓冲区拥塞时静默丢失。c_board的 I2C IRQ 优先级以减少与 USB 的冲突，并明确逻辑I2C0与物理I2C2的映射关系。rmcs_board使用的 HPM SDK 以恢复hpm5300evk相关板定义。影响与兼容性
CBoard、RmcsBoardPro和RmcsBoardLite新增I2C0主机接口与回调入口。c_board的逻辑I2C0实际由 STM32I2C2承载，但 host/firmware 对外名称保持不变。I2C0 跨板传输与传输恢复增强（含若干配套改动）
概述
本 PR 在主机、协议及两类板级固件（c_board / rmcs_board）间引入统一的逻辑 I2C0 传输通道，并强化传输的错误/超时恢复与上行缓冲策略。实现涵盖协议、主机 API、c_board（STM32 + DMA）与 rmcs_board（HPM + DMA）端的端到端支持，以及若干与构建、USB、中断相关的配套调整。修正了主机端 I2C 回调分发以避免覆盖/隐藏错误回调。
