* feat(windows): 添加中日英三语轮换 * fix(windows): 三语轮换改为快捷键开关并修复两端状态不同步 - 开关移到「快捷键 → 中英文切换」下的「允许中日英循环切换」，配置键改为 [keybindings] trilingual_cycle；输入模式恢复为中文/日文，二者互不影响 - 循环请求带显式标记位和请求方自身的中英/日文状态，Server 据此计算目标语言； 普通 VK_SHIFT 仍是中英切换，不再被误当成循环 - Server 开关在请求途中被关闭时仍回复，按中英切换处理，TSF 只丢弃后续排队按键， 不再超时重连 - 已发出的循环回复未被应用（含 Superseded）时走完整重连，避免日文状态两端不一致 - 循环切换补上光标处状态提示和标点同步 - 切换语言时复用暂存的另一语言会话，不在按键路径上重建引擎和打开 msime.db - 配置读取的语言与开关改为原子量；TrilingualCycleChanged 的能力过滤移到发送方 - 中日切换不再重发 TrilingualCycleChanged；结束组合被拒绝时不计入统计 --------- Co-authored-by: fanlusky <1730976608@qq.com>
