fix: Remove deprecated config.debug support

[lan17]

Summary

This is a follow-up cleanup to the logging work already merged to main.

• remove the deprecated config.debug compatibility path from runtime log level resolution
• remove debug from the plugin config schema and README examples
• update tests to treat logLevel as the only supported logging configuration knob

Why

config.debug is no longer needed. Keeping it around adds config ambiguity and unnecessary compatibility code for a path we do not want to support.

Verification

• npm run lint
• npm run typecheck
• npm test
