Go / build-and-release (push) Has been cancelled
Add LRU cache for serial lookups with dynamic scaling (v0.36.17)
- Add generic LRUCache[K, V] implementation using container/list for O(1) ops
- Replace random 50% eviction with proper LRU eviction in SerialCache
- Cache now starts empty and grows on demand up to configured limits
- Use [32]byte keys instead of string([]byte) to avoid allocation overhead
- Single-entry eviction at capacity instead of 50% bulk clearing
- Add comprehensive unit tests and benchmarks for LRUCache
- Benchmarks show ~32-34 ns/op with 0 allocations for Get/Put

Files modified:
- pkg/database/lrucache.go: New generic LRU cache implementation
- pkg/database/lrucache_test.go: Unit tests and benchmarks
- pkg/database/serial_cache.go: Refactored to use LRUCache
