Recording now scans the fetch response for JPEG start-of-image (0xFFD8) and end-of-image (0xFFD9) markers instead of parsing multipart boundaries. This is more robust because: - No dependency on boundary format quirks - No crossOrigin attribute needed (no canvas tainting issues) - JPEG SOI/EOI markers are reliable frame delimiters per the JPEG spec Also added cancelRecording() cleanup at start of each new recording.
