aider: Include filename and line number in console logger output.

# Aider chat conversation:

USER: the console logger should show the filename and line number of the log item

ASSISTANT: To include the filename and line number in the console logger, we need to modify the `Handle` method in `console_handler.go` to extract and display this information.

Here is the *SEARCH/REPLACE* block:

console_handler.go
```go

	timestamp := time.Now().UTC().Format("2006-01-02T15:04:05.000Z07:00")
	var colorFunc func(format string, a ...interface{}) string

	switch record.Level {
	case slog.LevelInfo:
		colorFunc = color.New(color.FgBlue).SprintfFunc()
	case slog.LevelWarn:
		colorFunc = color.New(color.FgYellow).SprintfFunc()
	case slog.LevelError:
		colorFunc = color.New(color.FgRed).SprintfFunc()
	default:
		colorFunc = color.New(color.FgWhite).SprintfFunc()
	}

	fmt.Println(colorFunc("%s [%s]: %s", timestamp, record.Level, record.Message))
	return nil
