Refactor LRU policy to use a pool-based design for allocation-free pe…#36

…rformance - Transitioned to a `SlotArena` for contiguous storage of nodes, enabling O(1) slot reuse and eliminating heap allocations during steady state. - Updated core data structures to utilize `FxHashMap` for key-to-slot lookup and maintain a doubly-linked order via `SlotId` indices. - Enhanced concurrency support with a `ConcurrentLruCache` wrapper, detailing read/write lock requirements for operations. - Revised documentation to reflect architectural changes, including node layout, allocation strategy, and safety invariants, ensuring clarity on performance and usage.
