[工作室录音机] 长时间录音会导致更新延迟、屏幕截图质量下降和最终完成速度缓慢

The Recorder event is strictly serial processing, and each operation also needs to wait for screenshot and page state collection, which causes a queue to accumulate during consecutive operations. 2. Studio polls for events every 500ms, further increasing the delay of the Timeline. 3. The operation and the preview screenshot are not bound to a stable transaction, and the screenshot collection time may be later than the actual operation. 4. The maximum limit for a single session screenshot asset is 128MiB, and high-resolution screenshots may reach the limit after about 20 to 25 operations, resulting in degradation of subsequent semantic descriptions. 5. Generate and Download use up to 20 screenshots by default, and the excess ones are silently cropped. 6. Stop is chained with waiting for the screenshot queue, event retrieval, AI description, persistence, and metadata generation. 7. Download reads the screenshots sequentially in the Renderer and generates a complete Base64 ZIP, which opens the save dialog box only after completion.
