Implement TTL (Time-To-Live) Support for Cache Entries ⏳

[0xnullifier]

Add support for expiring cache entries after a specified time period. This will help manage memory usage and ensure data freshness.

What is TTL?

Time-To-Live (TTL) specifies how long a cache entry should be considered valid. After the TTL expires, the entry should be removed from the cache.

You have to do the following:

• Add expiration to key-value pairs
• Implement background cleanup
• Add TTL queries
• Handle expired key access

TTL is hard topic so this will be counted as reopened multiple types issues.
