Add cache with LIFO replacement policy

[KevinMwita7]

Description

This PR adds a reusable LIFOCache implementation with the following features:

• Fixed size LIFO eviction policy using Deque as stack and HashMap as cache

• Time to live (TTL)

• Thread-safe operations using ReentrantLock

• Pluggable EvictionStrategy to control expired entry cleanup

• Eviction listener callback support for observing removals

• Hit and miss statistics tracking

• Builder for flexible configuration

• I have read CONTRIBUTING.md.

• This pull request is all my own work -- I have not plagiarized it.

• All filenames are in PascalCase.

• All functions and variable names follow Java naming conventions.

• All new algorithms have a URL in their comments that points to Wikipedia or other similar explanations.

• All new code is formatted with clang-format -i --style=file path/to/your/file.java
