Create @h3ravel/queue package for background job processing

Description

Introduce a new @h3ravel/queue package to manage background jobs, workers, and queue drivers.

The queue system should integrate with events and be usable independently of HTTP.

Consider taking a look at Bull/MQ

---

Goals

• Support background job processing
• Allow multiple queue drivers
• Integrate cleanly with events and CLI

---

Key Features

• Job and Queue contracts
• Queue dispatcher
• Worker implementation
• Retry, delay, and failure handling
• Optional event hooks (job started, failed, completed)

---

Tasks

• Create @h3ravel/queue package
• Define job and queue contracts
• Implement in-memory queue driver (baseline)
• Add worker runner
• Integrate with Musket CLI (future)
• Write tests for job lifecycle
• Document queue usage

---

Acceptance Criteria

• Jobs can be dispatched and processed
• Drivers are swappable
• No hard dependency on HTTP
• Typed job payloads supported
• Test coverage for core flows
