refactor: replace createjs.Ticker framerate with requestAnimationFrame idle management

refactor

Summary

Removes all createjs.Ticker.framerate calls and
replaces them with the existing requestAnimationFrame
render loop (_startRenderLoop).

Changes

• Removed createjs.Ticker.framerate = 60 (initial setup)
• Removed createjs.Ticker.framerate = ACTIVE_FPS
  in _resetIdleTimer
• Removed createjs.Ticker.framerate = IDLE_FPS
  in idle watcher
• Removed unused ACTIVE_FPS and IDLE_FPS constants
• _startRenderLoop() now handles idle/active rendering

Why This Is Safe

_startRenderLoop() at line 537 already uses
requestAnimationFrame and calls stage.update()
directly. It naturally pauses when stageDirty=false,
making explicit Ticker framerate control redundant.

Testing

• App loads and renders correctly ✅
• Idle mode works via rAF loop natural pause ✅
• User interaction restarts rendering ✅

Part of CreateJS migration effort for DMP 2026.

AFAIU,
binding to high frequency events like mousemove spawns multiple parallel loops, causing an rAF stampede that pushes the framerate to 600+ and freezes the browser.

Wrap _startRenderLoop() in a boolean lock (e.g., this._isRendering) so it can only queue one frame at a time:

Thanks for the review @lavjeetrai!

_startRenderLoop() already has a boolean
guard at line 537:

this._startRenderLoop = () => {
    if (this._renderLoopRunning) return;
    this._renderLoopRunning = true;

This ensures only one rAF loop runs at a
time, regardless of how many times
_startRenderLoop() is called from
mousemove events.

The existing lock prevents any rAF stampede.
Does this address your concern? 🙂

lgtm,thanks for clarification
