Perf/Optimize particle tracking and CharacterConfig caching

[Haerbin23456]

I used Codex to implement these changes. I reviewed all changes and tested them in game.

Overview

This PR contains two performance improvements for high-frequency gameplay paths:

1. Move two special particle target type checks out of every EntityList.Update call and perform them only when particle replacement is attempted.
2. Bind CharacterConfig for SpriteBank-managed Sprites when SpriteBank.Create / CreateOn completes, instead of repeatedly checking their resource source in CharacterConfig.For.

The intent is to preserve existing behavior while reducing repeated work.

Particle entity tracking

Previously, every entity update checked for NPC05_Badeline and CS10_HubIntro in order to redirect particle ownership to their shadow or booster.

These checks are now performed only when particle replacement is actually attempted. EntityList.Update only records the current entity.

CharacterConfig caching

For SpriteBank-managed Sprites, SpriteData and resource sources are already known when Create / CreateOn finishes.

The new implementation updates SpriteDataCache and binds CharacterConfig at that point. CharacterConfig.For can then normally return the cached binding directly.

Ordinary Image instances still use lazy resolution when their Texture reference changes.

CharacterConfig instances remain per-Sprite.

Testing

Manually tested in game with no functional issues observed.
