Pull request overview

Implements correct expression-tree emission for lambdas passed through IQueryable/Queryable chains by using Expression.Quote (instead of Expression.Convert) when converting a lambda to Expression<TDelegate>, addressing runtime failures described in issue #50.

Changes:

• Update the generator’s conversion emission to output Expression.Quote(...) for Expression<TDelegate> conversion nodes.
• Add generator- and runtime-level test coverage for an [ExpressiveProperty] body containing an IQueryable<T> chain with lambda arguments.
• Update verified generator output baselines to reflect Quote emission.
