Pull request overview
This PR adds documentation emphasizing the importance of idempotent message handling in Azure Service Bus messaging scenarios, specifically in the context of duplicate message detection and handling.
Key Changes:
- Added a note linking to an external article about idempotency in distributed systems

| The typical mechanism for identifying duplicate message deliveries is by checking the `message-id`, which can and should be set by the sender to a unique value, possibly aligned with an identifier from the originating process. A job scheduler would likely set the `message-id` to the identifier of the job it's trying to assign to a worker with the given worker, and the worker would ignore the second occurrence of the job assignment if that job is already done. | ||

The added note references an external third-party blog (particular.net) which may not align with Microsoft documentation standards. Consider either: (1) linking to official Microsoft documentation on idempotency if available, (2) incorporating the key concepts directly into this article, or (3) adding a disclaimer that this is third-party content. External links can break over time and may not receive the same maintenance as Microsoft documentation.

| This is where designing for idempotent message handling becomes critical. Idempotency means that processing the same message more than once produces the same result as processing it once, which helps prevent duplicate work or inconsistent state in distributed systems. When building message handlers, ensure that operations can safely be retried or repeated without adverse effects. |
