Add EF value converter and wireup

[buvinghausen]

Add new EntityFrameworkCore assembly which supports the value conversion of the two structs

[Copilot]

Pull request overview

Adds a new SequentialGuid.EntityFrameworkCore integration assembly to enable automatic EF Core value conversion for the library’s sequential GUID structs, plus tests validating converter registration and round-tripping.

Changes:

• Introduces SequentialGuid.EntityFrameworkCore with a ValueConverter<T, Guid> and a ModelConfigurationBuilder extension for convention-based registration.
• Adds ISequentialGuid<TSelf> (net8+) and updates SequentialGuid / SequentialSqlGuid with comparison and conversion operators to support the converter.
• Adds SequentialGuid.EntityFrameworkCore.Tests covering converter wiring and in-memory round-trip behavior.

Pull request overview

This PR introduces an Entity Framework Core integration layer for SequentialGuid and SequentialSqlGuid via value converters, and adds MongoDB BSON serializer support to round-trip these structs cleanly through MongoDB serialization.

Changes:

• Add SequentialGuid.EntityFrameworkCore project with EF Core convention-based value converter registration.
• Add MongoDB BSON serializers + a registration extension, plus tests validating registration and round-tripping.
• Introduce ISequentialGuid<TSelf> and update SequentialGuid/SequentialSqlGuid to implement it (including a Create(Guid) factory).
