Fix rendering race conditions where character sprites, pre-animations,
and paired character assets were displayed before being downloaded.
All assets referenced in an MS packet are now resolved and preloaded
into the browser cache before the animation timeline starts.

- Add unified assetCache module with session-wide promise caching
- Add preloadMessageAssets orchestrator for parallel asset resolution
- Cache fileExists HEAD requests so missing files aren't re-probed
- Preload all SFX (emote, shout, realization, stab) alongside sprites
- Use synchronous setEmoteFromUrl at all render transition points
- Graceful fallback to legacy setEmote if preloading times out
