v0.5.0

What's Changed

Native log/slog integration. This release replaces the custom field system with slog.Attr as the core type for error attributes. The logrus adapter has been removed.

Highlights

• slog.Attr everywhere — Use slog.String(), slog.Int(), slog.Group(), etc. directly in errors.Wrap() and errors.Errorf() alongside existing options.
• errors.Attrs(err) — Extract all attributes from an error chain for custom logging.
• errors.Log(ctx, logger, err) — Log an error at Error level with attributes and stack trace.
• errors.LogLevel(ctx, logger, level, err) — Same as above with an explicit level (Debug, Info, Warn, Error).
• New attribute options — Int64, Uint64, Float64, Any. Value is deprecated in favor of Any.
• Grouped attributes — Full support for slog.Group in errors, JSON marshaling, and %+v formatting (dot notation).
• slog.LogValuer — Errors implement LogValuer for native slog handling.

Breaking changes

• Custom Field types and FieldLogger are removed; use slog.Attr and *slog.Logger.
• LoggableError now requires Attrs() []slog.Attr instead of LogFields(FieldLogger).
• errors.Log(err, logger) replaced by errors.Log(ctx, logger, err).
• Package requires Go 1.21+.
• logrus adapter removed — see migration guide for a small custom adapter if needed.
