feat: add a SurrealDB queue driver

[ibourgeois]

Context

As a developer, I need queued jobs to work against SurrealDB so background processing can use the same persistence layer as the rest of the application when appropriate.

Acceptance Criteria

• A Laravel queue driver backed by SurrealDB is implemented.
• Jobs can be enqueued, reserved, completed, retried, and failed through the driver.
• Queue behavior is covered by automated tests.
• Worker setup and operational limitations are documented.

Notes

This is likely one of the riskier integrations and should be validated carefully.

Out of Scope

• Session storage
• Cache storage
