fix(audio): Prevent events from triggering one frame early

Events were triggering 16ms early in miniaudio playback because music_time
was advanced at the START of the frame, causing events to be checked against
future time but rendered into the current frame.

Fix: Delay music_time advancement until AFTER rendering audio for the frame.
This ensures events at time T trigger during frame [T, T+dt], not [T-dt, T].

Sequence now:
1. tracker_update(current_music_time) - Check events at current time
2. audio_render_ahead(...) - Render audio for this frame
3. music_time += dt - Advance for next frame

Result: Events now play on-beat, matching WAV dump timing.
