### [2026-07-25 10:54] Task: Fix TempoTrackLane height + clamp selection at column 0
- **Tóm tắt thay đổi:** Fix TempoTrackLane canvas height = 40px cố định (thay vì parentElement.clientHeight gây tràn). Wrapper `h-10 shrink-0 overflow-hidden` để không đẩy track lanes lệch TCP. Clamp selLeft/selRight/ruler handlers >= 0 để selection không vào vùng âm.

### [2026-07-25 10:44] Task: Zero lead-in, time ruler + tempo track split layout
- **Tóm tắt thay đổi:** Xóa leadInMargin (về 0) — time 0 tại mép trái, chỉ còn 8px PADDING_LEFT. TimelineRuler đơn giản thành time-only ruler (40px, chỉ hiển thị time labels). Thêm TempoTrackLane ngay dưới (40px, bars/beats/BPM). Selection overlay top từ 48→80px. Đồng bộ WaveformLane PADDING_LEFT=8/zoom.
