Automatically deduce Pydantic serializer in ctx.run

[igalshilman]

We already autodeduce Pydantic models in service handlers, let's auto detect pydantic models as a return values passed via ctx.run

Hey @ouatu-ro, is your recent change perhaps also resolved that?

Hi, only the serializer part. It's not introspecting the signature to attach the right model for deserialisation. Although that might be needed for production-ready use, as it may be unexpected to not have the deserialisation behaviour uniformly.
I could look into it, as I'll probably need this in production myself as an SDK user.

@ouatu-ro awesome, thanks!

Hi, I checked the code and ctx never takes inputs, so the previous pull request should be enough. While checking logic, I fixed all the type hints problems in the code in #57, but it seems to be clashing with the most recent changes and the other open PRs, so I'll leave it in draft for now.

@ouatu-ro ok, understood.
I'll ping you once main is stabilizing. We are currently exposing many new features and it touches a handful of places 😅
sorry about that!

[igalshilman]

Ok, I think that no more big changes are coming!

[ouatu-ro]

@igalshilman I'd say this issue is solved and #57 is ready for review.
