删除深度重算引擎；修好回放视频每帧重开文件导致的无法播放，运输控制改到状态轨主按钮 - What: 1) 彻底删除深度重算引擎：shared/.../record/depth.py（DepthRecomputer/DepthResult）与 depth_backends.py（BoxReplay/FingerReplay）、其专属测试 test_depth_replay.py，record/__init__ 不再导出，playback.py::replay_warnings 不再报 depth_recomputed；apps/studio/replay.py 由 515 行瘦身为只做读盘+游标+视频帧+提示，回放视图的 2D 面板只提供「原始图像」；session.json 的 depth.replay 由 recompute 改为 none；删除 31 个只剩深度使用的文案键（depth_*/warn_state_*/warn_reset_*），warn_config_changed 与 warn_sdk_changed 改为描述"由视频重算"；ui_check 深度段、studio 两个深度用例、test_playback 三例、drive_shared 的 test_depth_replay 与 reproduce.py 的深度段一并清理（shared 套件 150→134 项）。2) 无法播放的根因是 RecordingReader.video_frame_at 每帧都 cv2.VideoCapture 重开并 seek：小片段已 ~10 ms/帧，1080p H.264 每次 seek 需从关键帧解码（上百 ms），而播放每 33 ms 要一帧且全在 UI 线程上，视频因此看着不动；改为按分段缓存解码器、顺序帧用 read() 步进（实测 10 ms → 0.5 ms/帧）、跳转才 seek，新增 RecordingReader.close() 释放。运输控制按用户建议上移到状态轨主按钮：toolbar.set_run_role("playback") 使回放视图的主按钮变成「▶ 回放」/「⏸ 暂停」（实时视图仍是「▶ 运行」），点按以 1× 推进游标（墙钟计时，漏拍不变慢）、到末尾自动停，拖动游标/框选/滚轮/拖总览条经 ForcePlotsPanel.timeline_taken_over 自动暂停，空格键同效；曲线表头不再放第二个播放按钮；按钮样式在回放角色下不再套用"停止"的红色语义。 - Why: 用户要求先清掉深度重算引擎、并反馈"现在无法播放视频"，建议把上方播放按钮在历史回放形式下改为回放。 - Verification: ui_check.py 554 项 0 失败（新增 seek<250ms/步进<60ms 的解码预算、回放按钮文字随播放/暂停切换、手动拖游标即暂停、切回实时视图按钮恢复运行、按深度视图已移除）；test_ui_smoke.py 71 项 0 失败；drive_shared.py 134 项 0 失败（深度引擎用例随代码删除）；locale_studio.py 262 键齐全、zh==en；reproduce.py 退出 0；.repro/probe_play.py 实测按「回放」后 0.75 s 内游标推进 0.689 s、面板 12/12 帧都在更新；两张复核图（回放视图的「▶ 回放」、实时视图的「▶ 运行」）。 - Not in this change: 录制文件格式与 CSV 列序不变（raw_*.mp4 与 forces.csv 继续一起写）；「由视频重算」复核模式保留（它复用实时管线，是有状态、只能顺序前进的一遍）。
