refactor(chrg_north): 重构北向通信处理逻辑，增加配置版本校验机制

1. apps/chrg/applications/thread/chrg_comm.c: 新增通道配置版本递增逻辑，避免旧回码干扰新配置 2. apps/chrg/applications/thread/chrg_north.h: 更新config_version注释，补充用途说明 3. apps/chrg/applications/thread/chrg_north.c: 重构帧头解析函数，新增缓冲区操作辅助函数和通道切换复位逻辑 4. apps/chrg/applications/thread/chrg_roll_nor.c: - 新增超时、重发等宏定义 - 重构协议设置函数，增加返回值处理 - 新增回码匹配校验、邮箱清理、等待响应等辅助函数 - 重构自动请求逻辑，增加重试和配置版本校验 - 简化线程入口处理逻辑，统一回码释放流程 5. apps/chrg/codex_build.log: 记录本次编译的代码尺寸变化

+# Source CC_CLOSE 协议切换修改说明
+
+## 修改目标
+
+修正 Source 北向协议板的命令顺序，避免在 CC 保持 Attached 时直接重配
+`0xD0`。多通道同时切换时采用共享等待屏障，使保护时间并行发生，不按
+通道串行累计。
+
+## 本轮实施步骤
+
+### 第一步：统一状态命名
+
+断开 CC 的命令状态命名为 `IDX_SET_SOURCE_CC_CLOSE`，等待状态命名为
+`IDX_WAIT_SOURCE_CC_CLOSE`。`CC_CLOSE` 固定发送 `0x17=0x03`，不覆盖
+COM 保存的目标 `CC_Set`。
+
+### 第二步：调整停止态启动顺序
+
+Source 从停止状态启动以及 Sink 切换为 Source 时，不发送 `CC_CLOSE`，
+直接按以下顺序执行：
+
+```text
+IDX_SET_SOURCE_PD
+-> IDX_WAIT_SOURCE_PROTOCOL
+-> IDX_SET_SOURCE_CC_SET
+-> IDX_GET_SOURCE_VC
+```
+
+即先设置协议，收到 `0xD0` ACK 并完成保护等待后，再连接目标 CC。
+
+### 第三步：识别必须断开 CC 的切换
+
+COM 参数生效时，满足以下任一条件进入 `CC_CLOSE`：
+
+- 新协议为 PD/PPS 或 PD3.1/AVS，并且协议或 CC 线与上次不同。
+- 上次协议为 PD/PPS 或 PD3.1/AVS，本次切换为非 PD 协议。
+
+其它协议配置变化从 `IDX_SET_SOURCE_PD` 开始。标准协议仅改变电压、电流
+时直接更新功率板，不重复下发 `0xD0`。
+
+### 第四步：执行 CC_CLOSE 命令链
+
+COM先确定北向`sub`，协议或CC发生变化时进入
+`SOURCE_WORK_PROTOCOL_SWITCH`，不在COM中调用发送函数。北向轮询线程
+执行该Source工作状态，负责向南向功率板写入0V；标准协议还会在同一批
+命令中依次写模式和电流。提交成功后清零`set_volt`并进入
+`SOURCE_WORK_WAIT`，随后按已经选定的`sub`继续执行。
+
+需要断开 CC 的通道按以下顺序执行：
+
+```text
+IDX_SET_SOURCE_CC_CLOSE       发送 0x17=0x03
+-> IDX_WAIT_SOURCE_CC_CLOSE  等待共享保护时间
+-> IDX_SET_SOURCE_PD         发送 0xD0
+-> IDX_WAIT_SOURCE_PROTOCOL  等待协议 ACK 后保护时间
+-> IDX_SET_SOURCE_CC_SET     发送 0x17=目标 CC
+-> IDX_GET_SOURCE_VC         恢复 0x20 查询
+```
+
+每条设置命令仍需收到角色、命令、长度和 CRC 均正确的回码后才能推进
+`sub`；错误回码继续沿用现有丢弃和有限重发逻辑。
+
+### 第五步：多通道共享 CC_CLOSE 等待
+
+使用 `pending_mask` 和 `acked_mask` 管理本轮参与切换的 Source 通道。
+所有已登记通道都收到 `0x17` ACK 后，只启动一次 300 ms 保护等待。
+一个通道和四个通道的保护等待本身均为 300 ms；四通道只额外产生必要的
+命令收发时间，不会累计为四次 300 ms。
+
+### 第六步：握手稳定确认（本轮不修改）
+
+本轮不增加“连续两次 `0x20` 电压稳定后才进入 RUNNING”的新逻辑，继续
+使用现有 `chrg_source_parse()` 电压误差和重试规则。
+
+### 第七步：配置覆盖保护
+
+继续使用 `config_version` 防止 COM 新配置被旧回码推进。停止、角色切换
+或不再需要 `CC_CLOSE` 时，会把通道移出共享等待屏障，避免残留状态影响
+下一次启动。
+
+### 第八步：完整失败恢复（本轮不修改）
+
+本轮不增加握手总超时、再次 detach、整套流程最多重试两轮以及故障上报。
+单条北向命令仍使用现有的三次发送机制。完整恢复流程待单独验证后实施。
+
+## 时间参数
+
+| 参数 | 当前值 | 说明 |
+|---|---:|---|
+| `SOURCE_CC_CLOSE_WAIT_MS` | 300 ms | 从本轮最后一个有效 `CC_CLOSE` ACK 开始 |
+| `SOURCE_PROTOCOL_WAIT_MS` | 100 ms | 每通道收到 `0xD0` ACK 后并行等待 |
+| `NORTH_RESPONSE_TIMEOUT_MS` | 50 ms | 单次北向回码等待 |
+| `NORTH_REQUEST_MAX_RETRIES` | 2 | 首次发送外最多重发两次 |
+
+## 建议验证顺序
+
+1. 单通道停止态启动 PD，确认发送顺序为 `D0 -> 17(目标CC) -> 20`。
+2. 单通道 PD 改协议或 CC，确认顺序为 `17(03) -> 等待 -> D0 -> 17(目标CC) -> 20`。
+3. 单通道 PD 切换 QC/FCP/标准，确认切换前先发送 `17(03)`。
+4. 四通道连续生效，确认四路 `17(03)` 均回码后共享一次约 300 ms 等待。
+5. 连续执行 20 至 30 轮协议切换，检查是否仍出现 Source 芯片 PD 状态异常。
