Extract logging to pkg/log for use outside CLI: - Logger with Debug/Info/Warn/Error levels - Key-value pairs for structured logging - Customisable styling and output - Optional Core framework integration via Service Enhance pkg/errors with: - Wrap() and WrapCode() helpers - Code() for error codes - Op(), ErrCode(), Message(), Root() extractors - Standard library wrappers (Is, As, New, Join) Update pkg/cli/log.go to use pkg/log with CLI styling.
