[Enhancement] Optimize JitCompiler Cache Performance

[yasmramos]

Description

Profile and optimize the JIT compiler cache for better performance.

Task

• Profile current cache performance using JMH or similar
• Analyze cache hit/miss ratios with TailwindFXMetrics
• Implement improved eviction strategy (LRU is basic, consider LFU or adaptive)
• Add cache warming on application startup
• Document performance improvements with benchmarks

Files to modify

• src/main/java/io/github/tailwindfx/compiler/JitCompiler.java
• src/main/java/io/github/tailwindfx/TailwindFXMetrics.java

Success Metrics

• Improve cache hit ratio by 10%+
• Reduce average compile time by 15%+
