Cache with Expiration

Implement a basic in-memory cache where each key can have an optional time-to-live (TTL).
Keys should expire automatically after their TTL passes.

The cache should support:

• Set(key, value, ttl) — stores a key with a given TTL (0 = no expiration)
• Get(key) — returns value if key exists and hasn’t expired
• Delete(key) — deletes the key
