    JXL Decoder: Simplified Wrapper Using jxl-rs Native Output

Overview

Based on changes to jxl-rs that add:

FFI-friendly API integrated directly into JxlDecoderInner
DecoderState enum for runtime state tracking
Direct RGBA buffer output with JxlPixelFormat (U8, U16, F16, F32)
Streaming input with process_with_input() and decode_frame()
Helper methods on JxlBasicInfo (has_alpha(), animation_timing())

    How to Fix BrowserJS Abort Issue - V8 Termination Needs Yield Points

Summary

Good news: CL 7110745 is working correctly (all 31 bots passed). The issue is that V8's TerminateExecution() can only interrupt JavaScript at yield points, and the current sitegeist wrapper doesn't create them.
The Problem

When you call chrome.userScripts.terminate(), it invokes v8::Isolate::TerminateExecution(). However, this only works when JavaScript yields control back to the event loop.
