📝 Walkthrough

Walkthrough

The change updates three generic ThrowIfInvalid overloads for nullable-flow analysis. It adds [NotNull] annotations, updates the message-factory parameter type, suppresses related compiler warnings, and marks private exception helpers with [DoesNotReturn].

Changes

Validation contracts

Layer / File(s)	Summary
Annotate validation overloads src/Immediate.Validations.Shared/ValidationException.cs	The three generic ThrowIfInvalid overloads now accept [NotNull] T?. The message factory accepts Func<T?, string>. Compiler-warning state is managed around the methods, and private exception helpers use [DoesNotReturn].

Inline comments:
In `@src/Immediate.Validations.Shared/ValidationException.cs`:
- Line 59: Add explicit null guards to all three ThrowIfInvalid overloads in
ValidationException so null inputs always fail independently of validator
implementations; alternatively, if nullable inputs are intentionally supported,
remove the [NotNull] annotations and preserve that contract consistently.
