Context logging

package main

import (
	"context"

	"github.com/Deimvis-go/logs/logs"
	"go.uber.org/zap"
)

func main() {
	z, _ := zap.NewProduction()
	lg := logs.ZapAsKVCtxLogger(z.Sugar())

	ctx := context.Background()
	ctx = logs.CtxWith(ctx, "request_id", "abc-123")

	lg.Info(ctx, "processing request", "user_id", 42)
	// Output includes: request_id=abc-123 user_id=42
}
