v0.35.0 — queues & jobs

Move slow work off the request path: dispatch(new SendWelcome(id)) places a Job (or a plain function) on a queue, and a pluggable QueueDriver decides when it runs. Built-in drivers: SyncDriver (runs immediately — the default), MemoryDriver (defers; work() drains FIFO, inspect .jobs). dispatch takes { delay, queue }; a push-only custom driver is the seam for a real broker (e.g. Cloudflare Queues). New generator keel make:job. Core imports no broker, edge-safe.
