Add sousadiego11/easyqueue - Provider-agnostic desktop GUI for message queues

[sousadiego11]

EasyQueue is an open-source (MIT), cross-platform desktop app (Electron + React) for inspecting,
publishing, and debugging messages across message brokers from a single interface.

It's built provider-agnostic by design: the core defines shared abstractions (QueueClient,
QueueMessage, Connection) and each broker is a separate provider implementing the same interface.
SQS and RabbitMQ are supported today, with Azure Service Bus and Google Pub/Sub
already on the roadmap. the goal is N integrations, not just two.

Why it's worth including despite being early-stage:

• Architected to grow beyond SQS/RabbitMQ, unlike most single-broker tools currently listed.
• Local-first: connections stored locally, credentials encrypted, no data sent to external servers.
• Actively maintained, MIT licensed, with releases for Windows/macOS/Linux.
• Solves a recurring pain point (browsing/debugging DLQ messages without juggling the AWS console,
  the RabbitMQ management plugin, and other separate tools).

Happy to leave this open for community feedback per the contributing guidelines.
