Pull request overview
This PR wires a new backend-configuration path into Karya’s runtime, adding backend boot/lifecycle handling so the CLI can resolve a configured backend into a queue store and wrap worker execution with backend hooks.
Changes:
- Add
Karya.configure_backend+ accessors for backend class/options. - Introduce
Karya::CLI::BackendBootto resolve/instantiate backends, build queue stores, and run lifecycle hooks. - Update CLI worker boot + specs + docs to use backend configuration.
