Feat: Implement job queue + workers + drivers

[3m1n3nc3]

Background: Background processing with queues improves throughput for expensive operations.

Tasks:

• Define Job contract and serialization format.
• Implement QueueManager and drivers (sync, database, redis).
• Implement worker process/console command to process jobs.
• Implement retry/backoff and dead-letter handling.
• Add tests for sync and database drivers and worker behavior.
• Document how to create queued jobs and run workers.
• All tasks should placed in the packages/queue directory

Acceptance criteria:

• Jobs can be dispatched to different drivers.
• Worker processes jobs and honors retry/backoff.
• Interface mirrors laravel as much as possible, creating the familiar DX while also adding it own unique twists and turns.
• Tests available.

Difficulty: large

Hey @3m1n3nc3 👋, I’d love to take this on. I have experience working with background processing patterns, queues, and worker implementations, and I’m confident I can deliver the job contract, drivers, worker process with retry/backoff, and tests as described. Please assign me this issue so I can get started.
