Pull request overview

This PR standardizes Gorums runtime-facing panic/error strings to consistently use the gorums: prefix (per #301), and updates affected tests/docs to match.

Changes:

• Prefixes several runtime errors and panics with gorums: (config, manager, node, stream, correctable, test helpers).
• Updates config-related tests to assert the new prefixed error strings.
• Adjusts user-guide example error strings for nested calls.
