… node2image 潜伏 bug - 新增 utils/native_forward.py：合并转发整体判定（要么全部原生 forward、要么整体回退图片） - cached_messages 快查 → 本地 DB 解析频道，配合 REST 只读预检，突破缓存时间范围限制 - 配置项 use_native_forward（默认 True）与 native_forward_max_nodes（默认无限制） - 批量发送遵守 Discord 频道限流（5 条 / 5 秒） - send_group_forward_msg 接入原生转发，失败自动回退 node2image 图片方案 - send_private_forward_msg 保持图片方案（转发到 DM 尚未实测） - 修复 utils/discord_api.py：httpx 0.28 的 proxies→proxy、data→json（否则 delete/edit/forward 全部发错格式） - 修复 utils/node2image.py：v11 parser 无 parse_string，改用 parse_string_to_array - 版本号升至 1.0.2；新增 test_native_forward.py 13 例判定单元测试

概述
实现 issue #28：合并转发不再完全依赖
cached_messages，改用 Discord 原生 forward（message_referencetype=1，快照由服务端生成），可转发更久之前、未被缓存的消息。整体判定原则：要么全部节点原生转发，要么整体回退 node2image 图片方案。变更
utils/native_forward.py：can_native_forward()：逐节点无损判定（引用型 node、channel 经 cached_messages→本地 DB 解析、REST 只读预检存在性/可读性/类型/同服务器、节点数阈值），任一不满足返回Nonesend_native_forward()：批量POST /channels/{target}/messages，遵守频道限流节奏（5 条/5 秒）system.use_native_forward（默认True）、system.native_forward_max_nodes（默认无限制）send_group_forward_msg：先试原生转发，失败/降级自动回退图片send_private_forward_msg：保持图片方案（转发到 DM 尚未实测，注释说明）顺带修复（测试中发现的历史 bug）
utils/discord_api.py：httpx 0.28 已将proxies改名为proxy，且data=会发表单格式而非 JSON —— 修复前edit_message/delete_message/本功能全部会失败utils/node2image.py：v11 parser 无parse_string，图片回退渲染 message_id 节点必崩，改用parse_string_to_array测试
test_native_forward.py13 例全部通过（内联/不可转发类型/转发套转发/超阈值/跨服务器/DB+预检/混合等）message_reference.type=1+message_snapshots由服务端生成 ✅
