Title: Add Support for LiteDB Serialization/Deserialization

Body:

Hi,

I’d like to request support for serializing and deserializing Primitively value types with LiteDB. Currently, when attempting to use Primitively types (e.g., custom int-based value types) with LiteDB, I encounter the following error intermittently:

Method may only be called on a Type for which Type.IsGenericParameter is true.

Steps to Reproduce

1. Define a Primitively value type, e.g., public readonly partial struct CustomerId : int {}.
2. Use it in an entity class, e.g., public class MyEntity { public CustomerId Id { get; set; } }.
3. Attempt to insert and retrieve the entity using LiteDB (v5.x) with the default BsonMapper.

Expected Behavior

LiteDB should serialize/deserialize the Primitively value type to/from its underlying primitive value (e.g., int) seamlessly.

Actual Behavior

Serialization/deserialization fails with the above error, likely due to LiteDB’s BsonMapper not recognizing Primitively types natively. It might be serializing the whole CustomerId vs the internal Value.

It would be great if Primitively could provide built-in support or documentation for LiteDB integration to avoid manual converter registration for each type.

Thanks!

Thankyou so much for reporting this issue so thoroughly @koddek. I will give it some thought and get back to you.

I quickly threw together a basic generator that seems to work with LiteDB. All the code is in one file. It could help address the issue. Check out Primify

Apologies for not addressing this issue sooner. I was tied up in another project.

Primify is great. It's far from something that was thrown together!

If nothing else, my hopeless response seemingly caused you to develop a good solution yourself :-)

Thanks for the compliment. At first I threw it together because I knew nothing about source generation. But I gradually learned more and made it better, which led me to create Autoredi, which saves me so much time, code, and brain power. So thank you for creating Primitively and this exchange. You have made me a better programmer.
p.s. 'Apologies for not addressing this issue sooner.' No worries man. I understand completely :)

Thank you so much. I'm so glad it inspired you @koddek.

Autoredi is a really clever tool and very well written. I can see how it would be useful. I especially like the support for keyed services. Lots of developers aren't aware of them, but I they are so useful.

Thank you for taking the time to look at it. I appreciate the feedback. Yes, its very useful when using Feature based Architecture, for auto registering all those features right at its source.
