Breaking Changes

WithCleanup now takes a context.Context as its first argument: WithCleanup[T](ctx, interval) instead of WithCleanup[T](interval). The background goroutine stops when ctx is cancelled.
Has now returns a single error instead of (bool, error). Check err == nil instead of the old boolean return value.
Clear no longer returns an error (it never actually failed).
Cleanup is no longer part of the Cacher interface. It's still available on the concrete *Cache[T] returned by NewCache, or use WithCleanup for automatic background cleanup.

Update(key, value, ttl) bool — sets a key unconditionally, overwriting any existing value or expiration, even if the key is still live. Unlike Set, which refuses to overwrite a live key, Update always succeeds unless ttl is negative.
Len() int — returns the current number of keys in the cache, including expired keys that haven't been cleaned up yet.

Test coverage restored to 100% of statements, including the previously race-only branches in Get and Has's write-lock recheck path.
Module path is now github.com/parMaster/mcache/v2. Update your import:
```
import "github.com/parMaster/mcache/v2"
```
Go bumped to 1.25.1; testify updated to v1.11.1.
