Added a new section to the `README.md` demonstrating how to check the connection status using `EmailSender.IsConnected`.
Introduced a new `Email` record to simplify the representation of outgoing email messages. Updated the `EmailSender.Send` method to accept `Email` instead of `OutgoingEmailEvent`, with a `ToEvent()` method handling the conversion internally.
Refactored test cases to use the `Email` record, removing redundant properties (`Id` and `QueuedAt`) that are now auto-generated. Updated XML documentation to reflect these changes. Adjusted namespaces and added necessary `using` directives for proper referencing.
These changes improve code readability, maintainability, and centralize the mapping logic for outgoing email events.

The method extracts connection details (host, port, virtual host) from the URL and supports optional behavior for reconnection scenarios via the `onReconnect` parameter. Added `using System;` to support the `Uri` class.
Updated the `RabbitMqConfiguration` class to include:
- XML documentation for all properties, improving clarity.
- Default values for `QueueName`, `ExchangeName`, `RoutingKey`,
`DlqQueueName`, `DlqExchangeName`, and `DlqRoutingKey` to define

The `MailKit` package reference (version 4.17.0) was removed from the `DigitalData.MessagingService.Infrastructure.csproj` file. This change suggests that the functionality provided by `MailKit` is no longer required or has been replaced by an alternative solution.
A new project `DigitalData.MessagingService.Client` has been added, targeting `net462` and `net8.0`. The project includes metadata for packaging and distribution, such as `PackageId`, `Authors`, `Version`, and more.
The solution file `DigitalData.MessagingService.sln` has been updated to include the new project, with build configurations for `Debug|Any CPU` and `Release|Any CPU`. The project is nested under the `infrastructure` folder in the solution structure.
Added three new projects ("presentation", "core", and
"infrastructure") to the solution file with unique GUIDs.
Updated the `GlobalSection(NestedProjects)` to reflect the
new project structure, nesting the new projects under the
parent project with GUID `{02EA681E-C7D8-13C7-8484-4AC65E1B71E8}`.

lifetime independently, ensuring graceful shutdown. Updated the
`InitAsync` method to initialize dedicated channels and adjusted
RabbitMQ topology declarations to use the publish channel.
Replaced `_logger` with the injected `Logger` instance for
consistency and updated RabbitMQ operations to use the appropriate
channels with cancellation token support. Improved error handling
and logging in the consumer, and ensured acknowledgments operate
on the consume channel.
Simplified the class structure by removing redundant fields and
adopting C# 12 primary constructor syntax. Adjusted method
parameters for clarity and added comments to explain design
decisions. These changes enhance maintainability, scalability,
and reliability.
Removed `InitAsync` from `IOutgoingEmailQueue` to decouple RabbitMQ initialization from the interface. Replaced `AsyncIniteWorker` with the correctly named `AsyncInitWorker` in `DependencyInjection.cs` and introduced a new, improved implementation of `AsyncInitWorker`.
The new `AsyncInitWorker` class initializes the outgoing email queue consumer using an event-driven RabbitMQ approach, with enhanced logging and error handling. Removed the outdated `AsyncIniteWorker` class to streamline the codebase.
These changes improve code clarity, maintainability, and correctness.
Removed EmailSenderWorker and its configuration, including
EmailSenderWorkerConfiguration. Introduced AsyncIniteWorker
as a replacement, simplifying the design by removing
configuration-based toggling.
