v1.2.1

v1.2.1

修复 / Fixed

• 像素工具直接接受附件 ID：vision_ground / vision_detect / vision_crop / vision_present / vision_pixel_diff / vision_colors / vision_ocr / vision_long_screenshot_ocr / vision_trace / vision_extract_foreground 的 image 参数现在可以直接传上传图片的附件 ID（如 sha256:…），不再报 cannot read …/sha256:…: not found；vision_describe 的 paths 同样支持。
• Pixel tools accept attachment ids: the image argument of all ten pixel tools — and vision_describe's paths — now resolves uploaded-image attachment ids like sha256:… directly instead of failing with cannot read …/sha256:…: not found.
• 产物文件名不再互相覆盖：artifact 文件名在截断的 basename 之外追加完整输入的短指纹，64 字符 sha256 附件名与其裁剪产物不再塌缩成同一个 …-ground.png 互相覆盖。
• Artifact names no longer collide: stems append a short fingerprint of the full input, so a 64-char sha256 attachment name and its crops no longer collapse onto one …-ground.png and overwrite each other.
• vision_ground 对退化框（如 1 像素宽）自动重试一次，重试仍退化则明确报错。
• vision_ground retries once when the vision model returns a degenerate box (e.g. 1px wide) instead of accepting it silently.

改进 / Changed

• 模型引导可完整重放：「重新查看模型引导」现在先退出设置页（设置面板监听标准 Escape 键关闭）、重新弹出三步总览，并依次走完第 1 步（会话/文字模型）、第 2 步（视觉模型）、第 3 步（高亮视觉链）；引导状态改为 v2 步骤标记存储。
• The model guide replays fully: “re-view model guide” closes the settings modal (its panel closes on the standard Escape keydown), reopens the 3-step overview, and walks step 1 (session/text model), step 2 (vision model) and step 3 (highlighted chain) in order; guide state is stored as a v2 step marker.
• 设置卡片滚动流畅：长区块滚出视口即跳过绘制（content-visibility），各 provider 的模型选项列表缓存复用，卡片以稳定 props + memo 跳过无关重渲染；openrouter 单 provider 276 个模型下滚动不再卡顿。
• Smooth settings scrolling: long sections paint only when scrolled into view (content-visibility), per-provider model option lists are cached, and the memoized card skips unrelated re-renders — scrolling stays smooth even with 276 openrouter models.
