feat: enhance logging with caller information and add corresponding tests

- Add `path/filepath` and `runtime` imports
- Modify logging functions to include caller information
- Add `addCallerInfo` method to append file and line number to log messages
- Create a new test file `slog_test.go`
- Add tests for `addCallerInfo` method to verify it appends caller information correctly
