Pull request overview

This PR refactors ewrap to a more stdlib-first footprint by removing bundled third-party logger adapters and moving the circuit breaker into an opt-in subpackage, while adding fmt.Formatter + slog.LogValuer integrations and updating tests/docs/tooling accordingly.

Changes:

• Move circuit breaker implementation/tests out of the root package into breaker/, and remove the old threshold* implementation.
• Introduce (*Error).Format and (*Error).LogValue, plus a new ewrap/slog adapter subpackage for ewrap.Logger.
• Simplify dependencies (drop testify/zap/logrus/zerolog/etc.), add shared test fixtures, and significantly revise documentation + CI/lint configuration.

Makefile:107

• The target ci: .PHONY is not valid Make syntax for declaring phony targets and makes ci depend on a file named .PHONY. If you intended a phony ci target, define it as ci: and add it to the .PHONY: list (e.g., .PHONY: ci).

godoc:
	@echo "Generating documentation..."
	godoc -v -http=:8089 -play -index

ci: .PHONY
