fix(jm): PDF 改到合并转发外单独发送与 v3.18.1 发布准备

[69gg]

变更说明

修复 JM 自动提取的加密 PDF 在合并转发节点里下载失败的问题：转发退回「本子信息 / 解密密码」两个节点，加密 PDF 改为紧随转发之后单独发一条文件消息（v3.18.1）。

• build_forward_nodes() 不再接收 PDF 路径、不再生成 file 段；没有 PDF 时仍是「本子信息 / 状态」两个节点，行为不变。
• _send_result() 在转发之后单独发送 PDF：群聊走 send_group_file（群文件上传）、私聊走 send_private_file，独立文件消息可以正常下载；群聊下同一个 PDF 仍会进入群文件列表。
• 投递语义：转发被协议端明确拒绝时降级为「信息 + 密码两条普通消息」，文件照旧单独发送；转发遇到 delivery_uncertain / file_transfer_error 时不重发转发与信息/密码（转发可能已经送达），但文件此前从未发出、不算重复投递，仍会继续单独发送，避免整本下载白跑。文件自身投递结果未确认时直接上抛不重发，普通失败时补一条不写历史的「PDF 上传失败」提示。
• 状态与历史：返回值前缀改为三态（已发送合并转发 / 合并转发被拒，已改为普通消息发送信息与密码 / 合并转发投递结果未确认）+ PDF 文件已单独发送 或 PDF 文件发送失败；历史摘要写「PDF: 已单独发送加密文件（…，密码见转发节点）」，密码仍然只出现在转发节点、不进历史。
• 文档与测试同步：docs/pipelines.md、docs/configuration.md、README.md、jm_book 工具的 README 与 config.json 描述；tests/test_jm_sender.py 增加发送顺序、转发未确认仍发文件、文件未确认不重发等用例。
• CHANGELOG 记在 v3.18.1（v3.18.0 已发布，条目保持原样），版本号经 scripts/bump_version.py 3.18.1 同步到 pyproject / __init__.py / 两个 app 的 package.json + Tauri + Cargo 与各 lock。

影响范围

• 只影响 JM 自动提取与 jm_book(output_mode=send) 的发送形态；uid / info 模式与下载、合成、体积判定逻辑完全不变。
• 消息形态从「1 条合并转发（内含文件）」变为「1 条转发 + 1 条独立文件消息」；转发被拒时是「2 条文本 + 1 条文件」。
• 未改动 src/Undefined/webui/static/js/、apps/undefined-console/、apps/undefined-chat/ 的业务代码，apps 下只有版本号与 lock 变更。

关联 Issue

无。

自检

• uv run ruff check . 与 uv run ruff format --check . 通过
• uv run mypy . 通过（pre-commit hook 全仓执行）
• uv run pytest tests/ --cov 通过（按需运行定向用例：JM 相关 43 passed、CHANGELOG/发布脚本 25 passed，未跑全量覆盖率）
• 改动 apps/undefined-console/ 或 src/Undefined/webui/static/js/：不涉及业务代码
• 改动 apps/undefined-chat/：不涉及业务代码
• 涉及配置项：无新增配置项
• 涉及 WebUI / Tauri 界面：不涉及，无需截图

备注

• v3.18.0 的「转发节点里的文件可以直接下载」结论不成立：用户实测在 QQ 客户端下载失败，本 PR 按反馈把文件挪出转发；docs/configuration.md、docs/pipelines.md 中相应表述一并更正。
• 真机验证待用户在群聊 / 私聊确认独立文件消息可正常下载。
• 提交前 pre-commit 全过：ruff format/check + mypy（全仓）+ 两个 app 的 npm run check（Biome + TypeScript + Vitest + cargo fmt/check/test）。

Summary by CodeRabbit

• New Features
  • Encrypted PDFs are sent as separate file messages after a forward containing book information and the decryption password. In group chats, PDFs also appear in the group file list.
• Bug Fixes
  • When a forward is explicitly rejected, book information and the password are sent as ordinary messages. Uncertain forward deliveries are not resent, and PDF delivery is still attempted separately. File delivery errors are reported, and uncertain file deliveries are not retried.
• Documentation
  • Updated guidance to reflect the separate PDF delivery and fallback behavior.

📝 Walkthrough

Walkthrough

JM book delivery now sends book information and the decryption password in a merged forward, then sends the encrypted PDF as a separate file. Forward rejection, uncertain delivery, and file-send failures have distinct handling. Tests, documentation, and version declarations reflect the change.

Changes

JM PDF delivery

Layer / File(s)	Summary
Forward and separate file delivery src/Undefined/jm/sender.py, tests/test_jm_sender.py	The forward contains book information and the password, not the PDF. The sender attempts a separate file send and handles explicit forward rejection, uncertain delivery, and file-send failures. Tests cover group and private delivery and these outcomes.
Delivery documentation and release notes CHANGELOG.md, README.md, docs/configuration.md, docs/pipelines.md, src/Undefined/skills/shared.py, src/Undefined/skills/tools/jm_book/*	Documentation describes the separate PDF message, delivery outcomes, history wording, and file-size checks.
Release version declarations pyproject.toml, src/Undefined/__init__.py, apps/undefined-chat/*, apps/undefined-console/*	Project, package, and application versions change from 3.18.0 to 3.18.1.

Loading

Merge Risk: ⚪ Minimal · up to ae306

The PDF is sent separately after the information-and-password forward, with distinct fallback and uncertainty handling. No concrete merge-blocking issue remains in the supplied evidence; live QQ verification and the full test suite are still pending.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ae306

The separate upload retains the existing destination and access checks, and uncertain deliveries are not automatically repeated. No new security issue was established, but remote file retention and recovery behavior remain incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The inspected delivery sinks retain the caller's group or private-user target. Group delivery now uses the group-file upload surface. Successful uploads can also register a conversation-scoped cached attachment; temporary-download cleanup does not remove that copy or the remotely uploaded file.

Trust Boundaries and Controls

• observed — The standalone file path does not select a new destination. Group upload checks group access before invoking the provider, and private upload checks private access. Forward delivery likewise uses the shared destination checks. No authorization bypass was established in this exercised path.

Resilience and Maintainability Implications

• inferred — The split operation is not atomic: password forwarding may complete without the file, or the file may upload while password delivery remains uncertain. The implementation contains retries within an invocation, but the inspected path does not establish durable delivery reconciliation or cross-invocation idempotency. These are recovery limits, not proven introduced security defects.

Hardening Proposals

• proposed — Document retention and removal expectations for group-file uploads and cached attachments separately from temporary downloads, so cleanup is not mistaken for deletion of delivered copies.
