chore: prepare Desktop 0.12.12 release

Bump the desktop patch version and package matching Chinese and English notes
for image follow-up context, retained questions and answers, simpler Runtime
selection, and docked Git history with automatic project detection.

Review and align both feature matrices with the verified release range.
Agent stays at 0.11.23; no Agent release or LoongArch preview is included.
External knowledge probe tooling remains development-only, not a shipped
external knowledge-base feature.

Validation: 3911 tests passed, 66 skipped; typecheck, lint, and bilingual
release-note verification passed. Production builds use main-branch CI before
the immutable desktop tag; no local production package was built.

+`AgentRequest.imageContextArtifactIds` 传递最多 8 个成果 ID。图片消息可以没有正文，
+因此引用选择不使用过滤后的文字历史。队列在实际发送时使用当时的会话快照。
+普通文本历史契约保持 `role/content`；图片字节不进入历史 IPC，也不新增图片副本。
+
+Main 仅在 `capability === 'image-generation'` 时调用 `withImageConversationContext`。
+当前 `ContextManager` 已解析的显式附图优先；否则通过现有 `getArtifact` 加载引用的
+内联 PNG/JPEG，WebP 使用 Electron 解码为 PNG。缺失或不可用引用形成上下文提示，
+数据库等基础设施错误仍向上传递。读取不依赖会话的异步保存进度，因为成果已在发送
+`artifact` 事件前由 Main 保存。

+公开成果事件和消息 metadata 保存，不新增表、迁移、服务端 ID 或 Runtime 会话缓存。
+它是该回复的展示事实，不进入下一轮提示词。

+## 上游请求

+`ModelAgentRuntime` 将已有文字历史作为会话数据加入提示词，并把本轮要求放在末尾。
+不从头截断组合提示词而丢掉最后的修改要求；服务商自己的长度和资源限制仍然有效。

+`/images/generations`。质量、认证及自定义请求字段继续走原有配置合并。

+显式回传上下文不表示上游提供或保存了服务端会话；无法据此保证像素级不变。

+# 图片上下文提示
+
+遵循根目录 [UI-DESIGN.md](../../../UI-DESIGN.md)。
+
+- 仅在某次成功生成确实缺少部分上下文时，在对应助手回复底部显示低强调文字。
+  正常使用上下文不显示警告，也不声称上游“不支持上下文”。
+- `reference-unavailable`：部分历史图片无法读取，本次仅使用可用的图片与文字上下文。
+- `editing-unavailable`：上游不支持图片编辑，本次按文字要求生成，未使用参考图片。
+- 使用共享 `--text-muted`、`--font-caption` 和间距令牌。不加警告卡片、闪烁、
+  `alert`、`aria-live`、弹窗或应用通知。文本保留在消息中并随会话恢复。
+- 发送和生成继续可用；真实请求失败仍采用原来的错误及重试交互，不生成成功提示。
+- 文案具备简体中文、英文两套翻译。本轮显式附图和新对话继续使用现有入口，
+  不增加模式开关或第二次确认。
