Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Optimize=20BloomPostProcessor=20ini?=
 =?UTF-8?q?tialization?=
MIME-Version: 1.0

The `BloomPostProcessor.init` method was fetching shader files sequentially, leading to unnecessary latency.
This change parallelizes the fetching of threshold, blur, and composite shaders using `Promise.all`.

Benchmark results (simulated network delay of 100ms):
- Baseline: ~300ms
- Optimized: ~100ms
- Improvement: ~66% faster initialization phase.

Affected files:
- `public/utils/bloomPostProcessor.ts`
- `utils/bloomPostProcessor.ts`
