Stable public release. API is frozen.

Changed #

• Version aligned with the rest of the super_cache family.
• Documentation improvements.

Added #

• FakeCache<K,V> — synchronous in-memory Cache<K,V> implementation for unit tests. No eviction; all entries survive until explicitly removed or TTL elapses. Exposes gets, puts counters and a reset() helper.
• ManualClock — injectable time source. Pass it to FakeCache and call advance(Duration) or setTime(DateTime) to control TTL expiration without Future.delayed. Makes TTL tests deterministic and instant.
