Function spawn_hook

Spawn an async persistence task with the configured timeout.

The task’s result is never awaited by the caller. Errors and timeouts are logged at WARN; the query path is unaffected.

This helper is public so the production super::manager::WorkspaceManager and custom SqrydHook impls can share the same timeout-and-absorb pattern.
