hook: warn when hook.<friendly-name>.jobs is set
Issue a warning when the user confuses the hook process and event namespaces by setting hook.<friendly-name>.jobs. Detect this by checking whether the name carrying .jobs also has .command, .event, or .parallel configured. Extract is_friendly_name() as a helper for this check, to be reused by future per-event config handling.
