Consistent naming patterns

Follow consistent naming conventions throughout the codebase to improve readability and maintainability:

1. Client property names should be singular, not plural:

   // Good
   IObservableOrganizationHooksClient Hook { get; }
   // Not
   IObservableOrganizationHooksClient Hooks { get; }
   

2. Method names should include appropriate verbs and be concise:

   // Good
   Task<string> GetSha1(string owner, string name, string reference);
   // Not
   Task<string> Sha1(string owner, string name, string reference);
   

3. Always use nameof() for parameter validation instead of string literals:

   // Good
   Ensure.ArgumentNotNull(client, nameof(client));
   // Not
   Ensure.ArgumentNotNull(client, "client");
   

4. Use descriptive parameter names that clearly communicate purpose: ```csharp // Good - clear distinction between concepts IObservable Delete(string owner, string name, int number, int reactionId); // Not - ambiguous IObservable Delete(string owner, string name, int number, int reaction);

// Good - clearly identifies repository ID Task Transfer(long repositoryId, RepositoryTransfer transfer); // Not - too generic Task Transfer(long id, RepositoryTransfer transfer);

5. **For pull request operations, use 'number'** instead of 'id' to avoid confusion with the internal ID:
```csharp
// Good
IObservable<PullRequest> Get(string owner, string name, int number);
// Not
IObservable<PullRequest> Get(string owner, string name, int pullRequestId);

These conventions help maintain a consistent codebase, reduce confusion, and make the API more intuitive for consumers.
