…Pool to InactivePool - Add TinyLFU frequency sketch with Count-Min Sketch implementation - Create FrequencyTracker trait with TinyLFUTracker and NoOpTracker implementations - Add optional frequency tracking to BlockRegistry with touch() and count() methods - Implement transfer_registration() for internal pool transfers without tracking - Rename RegisteredPool to InactivePool to better reflect dormant block semantics - Update all references across manager, registry, and test utilities All 41 tests passing. Phase 1-3 complete for block manager v2 refactoring.
…ager Replace constructor-based approach with fluent builder API: - Add BlockManagerConfigBuilder with backend selection enum - Support HashMap, LRU, and MultiLRU backend configurations - Automatic LRU capacity sizing (equals block_count to prevent eviction) - Custom MultiLRU frequency thresholds with validation - Frequency tracker size validation (2^18 to 2^24, power of 2) - Comprehensive test suite for all builder configurations Provides clean API: BlockManager::builder().block_count(100).with_lru_backend().build() Resolves ergonomic issues with previous new() and new_with_multi_lru() constructors.

- Replace Mutex with parking_lot::RwLock in InactivePool and BlockRegistry for improved concurrent read performance - Add #[inline] annotations to hot path methods including all drop implementations and registry lookups - Pre-allocate vectors in bulk operations (match_blocks, allocate_blocks) - Add comprehensive Criterion benchmarks for registration, lookup, drop, and allocation operations - Fix clippy warnings: remove unused imports, add Default implementations, use modern Rust patterns (is_multiple_of, Result matching) These optimizations address high variance in benchmarks and improve contention in multi-threaded scenarios by allowing concurrent reads while maintaining write safety.
