Replace inline WebSocket URL construction with Config.getWebSocketUrl()
helper method in all command files. This eliminates code duplication
and ensures consistent URL formatting across the CLI.
Files updated:
- annotate.zig, dataset.zig, experiment.zig, logs.zig
- narrative.zig, prune.zig, queue.zig, requeue.zig
- sync.zig, validate.zig, watch.zig
The helper properly handles ws:// vs wss:// based on port (443).
