* [Bump Akka.Hosting to 1.5.59](https://github.com/akkadotnet/Akka.Hosting/releases/tag/1.5.59)
* [Fix lock contention and high CPU usage during concurrent event persistence](https://github.com/akkadotnet/Akka.Persistence.MongoDB/pull/428)

**Performance Fix: Reduced BSON Serializer Lock Contention**

Fixed a critical performance issue where concurrent persistence operations would cause high CPU usage due to lock contention in the BSON serializer. Previously, `FullTypeNameObjectSerializer` would repeatedly register discriminators for types that were already registered, acquiring write locks unnecessarily.

Changes:
- Added tracking of already-registered types to skip redundant registration
- Made `FullTypeNameObjectSerializer` public with a static `RegisterNewTypesToDiscriminator()` method for pre-registration at startup
