Introduce a configuration field to control the verbosity and tracing level for awf, enabling enhanced debugging. This should allow users to adjust the amount of logging or tracing output as needed, similar to the request in the related gh-aw issue #2401.

Requirements:

• Add a new field in awf configuration for verbosity/tracing.
• Allow multiple levels (e.g., error, warning, info, debug, trace).
• Document usage with relevant examples.
