Real beat sync — not decoration

Every uploaded or generated audio file runs through librosa to extract BPM, downbeats, verse/chorus boundaries, and drop detection. The screenwriter aligns scene starts to bars while letting lyric timing always win.

• ▸BPM and downbeat detection via librosa beat-track (tightness=60).
• ▸Verse / chorus / bridge boundaries via chroma SSM agglomerative clustering.
• ▸Drop detection on RMS energy peaks at bar boundaries.
• ▸Always-on across Animated, Slideshow, and Character modes — no toggle, no extra credits.
