采集循环只认新帧，选区统计移到数值卡，状态栏改为会过期的通知行 - What: 1) 选区统计不再挤在曲线下方（中文长句会顶出面板右边界）——框选后三个数值卡的大号数字变成该窗口的峰值、下方小字为该窗口的均值·σ（chart.selection_detail），峰值语义放在卡片 tooltip；曲线下方只保留「选区 4.00s / 121 点」（完整一行留在它的 tooltip 里）。「全程总览」不算选区（那是默认适配），此时卡片回到"游标处样本"；切换单位/换数据源/返回最新都会正确切回。2) 上方的 63.0 FPS 是采集循环自己的轮询速率，根因是同一帧被反复当成新样本：CaptureSource.read_latest 返回后台线程的最新帧，没有新帧时把同一帧再给一次，循环未做判断，于是 30 fps 的设备录出约 63 行/秒（frame_id 还各不相同）。新增 _capture_sequence()：读 capture_source.status.last_seq，计数未变即"还没有新帧"，睡 2 ms 重试、不进处理链、不发 packet；只有带后台读取线程的实时相机有该标记，视频文件是同步解码、每次都取下一帧，因此忽略（行为不变）。packet.fps 改为速率 (窗口帧数-1)/(首末到达差)，窗口 1 s——按"1 秒内到达几帧"数数会系统性偏大。容器速率仍取传感器配置值，与此层无关。3) 底部状态栏只留一次性通知：删除右下角常驻「配置 sensor.json」（顶栏摘要按钮已写明），删除与顶栏重复的 status.run_started（运行中（0））与 status.connecting（正在连接…）；QStatusBar 换成 _NoticeBar——Qt 的 showMessage(text) 默认 msecs=0 表示永不消失，这正是那句「运行中（0）」一直挂到底部的原因，子类统一补 6 秒超时；status.units_raw_fallback 之前每帧都发（等于永久占住通知行），改为每次运行只提示一次。附带修复：英文下表头模式名被截断（长句移入 tooltip，标签只留模式名 chart.mode_*_tip）；数据源切换后曲线下方的选区文案会残留，改为在 _on_source_changed 里清零。 - Why: 用户评审 3 点——选区统计显示不全、顶部 fps 应受硬件限制最大 30、右下角配置文件名与左下角「运行中（0）」和顶栏信息重复。第 2 点查出根因是重复采样（数据缺陷，不只是显示问题），修掉后设备速率与记录行数才真正一致。 - Verification: ui_check.py 546 项 0 失败（新增：选区统计在卡片、卡片小字不裁切、状态栏无常驻标签且消息过期、顶栏 FPS 即 packet 交付速率、表头模式名中英不裁切）；test_ui_smoke.py 71 项 0 失败（新增选区读数与通知行过期两例）；drive_shared.py 148 项 0 失败（新增 shared/tests/test_worker_frame_rate.py：同一帧返回 3 次时 packet 数≈交付帧数，去掉判据为 11317:39，且 fps 与交付速率一致）；locale_studio.py 267 键齐全、zh==en、prefs 对齐；reproduce.py 退出 0；ui_snapshot.py 新增 --select A,B，六张复核图（选区中英、实时、录制中、回放、标定 1280x720）。 - Not in this change: 录制文件格式与 CSV 列序不变；去重只影响"哪些帧算一帧"，视频文件源行为不变；曲线下方不再显示三通道峰/均/σ（数值在卡片上，完整一行在 tooltip 里）。
