chore: integrate and configure Pyroscope profiling

- Add README.md with instructions for getting started with Pyroscope
- Create docker-compose.yaml with Pyroscope service configuration
- Change Pyroscope server address in main.go from `http://pyroscope:4040` to `http://localhost:4040`
- Adjust health check interval in docker-compose.yaml from `30s` to `5s`

+Pyroscope is an open source continuous profiling platform. It will help you:
+
+- Optimize your application's performance
+- Debug hard-to-reproduce issues
+- Understand your application's bottlenecks
+- Monitor your application's performance over time
+- And much more!
+
+## Download and configure Pyroscope
