Changes

What's Included

• ModWorker — new worker handling mod.install and mod.uninstall jobs; downloads files into the workload's bind-mounted volume via InjectFile/RemoveFile
• RuntimeAdapter.ListRunning — new interface method; Docker implementation seeds the in-memory repo from running container labels on daemon startup, preventing state loss after restarts
• Log stream fix — Logs() now passes Since=container.State.StartedAt when following, so reconnects don't re-stream historical lines
• Log tailer fix — tail() now closes the lines channel via a WaitGroup when both scan goroutines exit, allowing the tailer to restart cleanly after a server stop/start; reconcile interval reduced from 10s to 3s
• Redis retry fix — Retry() was reading Attempts=0 back from Redis causing infinite retries; fixed by incrementing before re-enqueuing
