6da7227f9b
This is a large-scale refactoring across the codebase that replaces the custom `gperr.Error` type with Go's standard `error` interface. The changes include: - Replacing `gperr.Error` return types with `error` in function signatures - Using `errors.New()` and `fmt.Errorf()` instead of `gperr.New()` and `gperr.Errorf()` - Using `%w` format verb for error wrapping instead of `.With()` method - Replacing `gperr.Subject()` calls with `gperr.PrependSubject()` - Converting error logging from `gperr.Log*()` functions to zerolog's `.Err().Msg()` pattern - Update NewLogger to handle multiline error message - Updating `goutils` submodule to latest commit This refactoring aligns with Go idioms and removes the dependency on custom error handling abstractions in favor of standard library patterns.
