Subject: [PATCH] fix: cleanup round - full width layout and paste operation
 bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed two issues:
1. Made audio editor full width by removing max-w-6xl wrapper
2. Fixed insertBufferSegment bug where paste operation had incorrect
   target buffer indexing causing corrupted audio after paste

Changes:
- app/page.tsx: Removed max-w-6xl constraint for full-width editor
- lib/audio/buffer-utils.ts: Fixed paste buffer copying logic
  * Corrected target index calculation in "copy after insert point" loop
  * Was: targetData[insertBuffer.length + i] = sourceData[i]
  * Now: targetData[insertSample + insertBuffer.length + (i - insertSample)] = sourceData[i]
