Fixed issue where Play/Pause buttons didn't update after clicking on waveform or timeline slider. Problem: - seek() in useAudioPlayer hook only updated currentTime - But player.seek() now auto-starts playback - React state (isPlaying, isPaused) wasn't updated - Transport buttons showed wrong state (Play instead of Pause) Solution: - Update isPlaying = true and isPaused = false in seek callback - Now transport buttons correctly show Pause icon when seeking - UI state matches actual playback state 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
