Syoyo Fujita d04efdf8d3 Add EM_JS synchronous progress callbacks for Tydra conversion ...

- Add EM_JS functions in binding.cc for direct C++ to JS progress reporting
  - reportTydraProgress: mesh conversion progress (current/total, stage, name)
  - reportTydraStage: conversion stage changes
  - reportTydraComplete: conversion completion with counts
- Update TinyUSDZLoader.js with callback options:
  - onTydraProgress, onTydraStage, onTydraComplete
  - setTydraProgressCallback/setTydraStageCallback/setTydraCompleteCallback methods
- Integrate callbacks in progress-demo.js for real-time UI updates
- Add design document for JS/WASM synchronous event update patterns

This enables real-time progress updates during Tydra scene conversion
without requiring ASYNCIFY, using Emscripten's EM_JS for synchronous
JavaScript calls from C++.
