kayjaydee a4427d91a7 feat(04-00): minimal chain_spark particle assets for codec spike ...

- Author chain_spark.particlesystem (Spawners[1] -> SpawnerId=chain_spark)
- Author chain_spark.particlespawner (required co-asset, Sphere/BlendAdd, embedded Particle with Animation[0,100])
- Bundle 4x4 placeholder chain_spark.png in Particles/ to satisfy CommonAssetValidator.TEXTURE_PARTICLES
- ShadowJar packages all three at exact case-sensitive path Server/Particles/

Deviation from plan: research assumed only one .particlesystem file needed. Decompiled codec
shows ParticleSpawner is a SEPARATE asset (.particlespawner) referenced by SpawnerId, plus
Particle.Texture is validated against CommonAssetRegistry (must exist as Particles/<name>.png).
Both required for the spike to validate end-to-end. Documented in SPIKE-FINDINGS.
