Trigger clip:selected event on resize completion

[ferozhussain]

The clip selection behavior to trigger the clip:selected event not only when a clip is clicked, but also when a clip resize or rotation operation is completed. This ensures that applications can respond to all types of clip interactions through a single event handler.

Changes

Updated the onPointerUp method in the Player class to trigger the setSelectedClip method when:

A clip is clicked (existing behavior)
A clip scaling operation is completed
A clip rotation operation is completed

This makes sense. I'll test and get this merged.

We should separate selection from state updates by:

1. Keeping clip:select for ONLY initial selection events (triggered on pointer down)
2. Adding a new clip:update event for state changes after manipulation (triggered on pointer up)

Proposed clip:update payload structure:

{
  previous: {
    clip: { ...previousConfig },
    trackIndex: previousTrackIndex,
    clipIndex: previousClipIndex
  },
  current: {
    clip: { ...currentConfig },
    trackIndex: currentTrackIndex,
    clipIndex: currentClipIndex
  }
}

This separation follows standard event system patterns, improves code clarity, and future-proofs our implementation.

Agreed
