• Add support for converting MapRemoteValue and ObjectRemoteValue to generic dictionary types
• Implement ConvertRemoteValuesToDictionary method for dictionary conversion logic
• Add comprehensive tests for populated and empty dictionary conversions

Add dictionary conversion for RemoteValue types

• Added two new conversion patterns for MapRemoteValue and ObjectRemoteValue to generic
 dictionary types
• Implemented ConvertRemoteValuesToDictionary private method to handle dictionary conversion with
 key-value pair extraction
• Uses reflection to dynamically invoke ConvertTo methods for both key and value types

dotnet/src/webdriver/BiDi/Script/RemoteValue.cs

Add RemoteValue to dictionary conversion tests

• Added test for converting MapRemoteValue to Dictionary<string, int> and `IDictionary<string,
 int>`
• Added test for converting empty MapRemoteValue to dictionary
• Added test for converting ObjectRemoteValue to Dictionary<string, bool> and
 IDictionary<string, bool>
• Added test for converting empty ObjectRemoteValue to dictionary

dotnet/test/common/BiDi/Script/RemoteValueConversionTests.cs

Description

ConvertRemoteValuesToDictionary assumes each entry has exactly two elements and relies on
null-forgiving reflection calls, which can crash with non-actionable exceptions if protocol data or
reflection lookup is unexpected.

Code

dotnet/src/webdriver/BiDi/Script/RemoteValue.cs[R158-173]

+    private static TResult ConvertRemoteValuesToDictionary<TResult>(IReadOnlyList<IReadOnlyList<RemoteValue>>? remoteValues, Type dictionaryType)
+    {
+        var typeArgs = dictionaryType.GetGenericArguments();
+        var dict = (System.Collections.IDictionary)Activator.CreateInstance(dictionaryType)!;
+
+        if (remoteValues is not null)
+        {
+            var convertKeyMethod = typeof(RemoteValue).GetMethod(nameof(ConvertTo))!.MakeGenericMethod(typeArgs[0]);
+            var convertValueMethod = typeof(RemoteValue).GetMethod(nameof(ConvertTo))!.MakeGenericMethod(typeArgs[1]);
+
+            foreach (var pair in remoteValues)
+            {
+                var convertedKey = convertKeyMethod.Invoke(pair[0], null)!;
+                var convertedValue = convertValueMethod.Invoke(pair[1], null);
+                dict.Add(convertedKey, convertedValue);
+            }

Evidence

PR Compliance ID 12 requires validating required inputs early and failing fast with actionable
errors. The new conversion code uses null-forgiving operators for reflection/activation and indexes
pair[0]/pair[1] without validating the structure, which can throw
NullReferenceException/IndexOutOfRangeException instead of a clear error.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`ConvertRemoteValuesToDictionary` currently assumes inputs are well-formed (each `pair` has 2 elements) and uses null-forgiving reflection/activation. If data is malformed or reflection lookup fails, it can throw non-actionable exceptions like `IndexOutOfRangeException`/`NullReferenceException`.
## Issue Context
This conversion is fed by protocol-derived `RemoteValue` payloads and should fail fast with clear, actionable errors when inputs are invalid (per PR Compliance ID 12).
