In `@src/Undefined/api/app.py`:
- Line 85: Update RuntimeAPIServer.start() and the OneBotFileStore.publish()
URL-mode flow so file-token URLs use HTTPS when TLS is configured or terminated
by a reverse proxy; otherwise reject URL mode for non-loopback hosts instead of
creating an unencrypted web.TCPSite, while preserving loopback behavior.
In `@src/Undefined/api/routes/onebot_files.py`:
- Around line 51-56: Add the X-Content-Type-Options header with the value
nosniff to the download response headers in the route’s existing headers
mapping, alongside Content-Type and the other security headers.
In `@src/Undefined/attachments/render.py`:
- Around line 302-305: Update dispatch_pending_file_sends and both handlers to
preserve the number of attachments successfully delivered before a later
FileTransferError. Propagate that count or an equivalent partial-delivery marker
with the error, retain the existing body-sent behavior for mixed body-and-file
sends, and return a partial-success result while preserving the sent marker when
earlier attachments were delivered.
In `@src/Undefined/onebot/client.py`:
- Line 316: Update the exception handling around the delivery operation to catch
asyncio.CancelledError separately from OneBotDeliveryUncertainError; record the
uncertain delivery key if needed, then re-raise the original cancellation so
downstream handlers cannot convert it into a normal tool result.
In `@src/Undefined/onebot/file_store.py`:
- Line 117: Update the URL construction around FILE_ROUTE and the token-bearing
return to use a configurable HTTPS base URL instead of hardcoding http://;
ensure URL-mode tokens are never emitted over plaintext transport, rejecting
non-loopback configurations when TLS is not configured.

- Download route now sends X-Content-Type-Options: nosniff. - dispatch_pending_file_sends attaches the delivered count to FileTransferError; both message tools report partial delivery and keep the sent marker. - External cancellation propagates as CancelledError again instead of being rewritten into OneBotDeliveryUncertainError, while the uncertain key and sent marker are still recorded; a send-stage budget timeout stays uncertain.

In `@src/Undefined/skills/toolsets/messages/send_message/handler.py`:
- Around line 217-222: Track body delivery with a new body_sent flag in both
relevant file-transfer exception paths: initialize it false and set it true only
after the body sender completes successfully. Use body_sent instead of
has_delivery_message when constructing transfer results, ensuring a failed body
send with no delivered files returns the transfer error without the “正文已发送”
prefix.

has_delivery_message only reflects rendered content; when the body send itself raises FileTransferError (inline local media goes through _call_api), both handlers no longer claim the body was sent or report 0/0 attachments.

背景
Bot 发送本地文件（渲染图、语音、压缩包等）此前要求 NapCat / 协议端与 Bot 共享文件系统，跨容器部署只能自行挂载路径。本 PR 新增统一文件传输层，为本地文件提供
local/url/stream三种发送方式，默认保持local以兼容旧部署。变更内容
[onebot].file_send_mode（local/url/stream）与[onebot].file_send_host，支持ONEBOT_FILE_SEND_MODE/ONEBOT_FILE_SEND_HOST环境变量与热更新（按投递快照生效）；url/stream必须显式启用，WebUI 配置表单同步提供下拉选择。url模式复用 Runtime HTTP 监听，将本地文件复制为独立临时副本；新增单文件令牌下载路由GET/HEAD /api/v1/onebot/files/{file_id}?token=...，有效期 16 分钟，支持 HEAD / Range / 重复读取。令牌只授权对应文件，不能调用其他 Runtime API；访问日志不记录查询串，停止时清理本实例缓存。stream模式通过既有 OneBot WebSocket 按 64 KiB 分块上传并逐块等待确认，完成后独立请求并校验协议端路径、大小与 SHA-256；同一 Bot 串行上传、纯文本不受影响、不支持零字节文件；协议端不支持扩展时明确报错并提示改用其他模式。FileTransferError会穿透私聊 / 群临时会话回退、附件派发与 Bilibili 发送链路，并把可展示说明反馈给模型。chunk_data脱敏规则，修复脱敏替换未正确回填捕获组的问题；接收循环停止时统一让挂起请求失败退出。测试
