⚡ Bolt: Precompute static prefix to optimize getFullKey performance

[suranig]

💡 What: Precomputed the base prefix inside createCacheHandler and simplified getFullKey to use basic string concatenation instead of dynamic array allocation, .filter(), and .join().

🎯 Why: getFullKey is on the absolute hottest path (called on every cache fetch). Continuously allocating arrays and iterating through them for statically known values (prefix, version) generates unnecessary CPU overhead and V8 garbage collection pressure.

📊 Impact: Expected to decrease CPU time and memory allocation overhead per cache lookup, yielding more consistent latency at scale.

🔬 Measurement: Verify correctness by ensuring unit test suite npm run test passes (specifically createCacheHandler.test.ts). You can profile memory allocations during load testing to confirm reduced garbage collection sweeps.
