aider: Fix undefined `slog.Field` error in `console_handler.go` by implementing the `slog.Handler` interface correctly.

USER: ../console_handler.go:15:77: undefined: slog.Field

ASSISTANT: To fix the undefined `slog.Field` error in `console_handler.go`, we need to ensure that the `ConsoleHandler` implements the `slog.Handler` interface correctly. The `Log` method should be replaced with the `Handle` method, which takes a `slog.Record` as an argument.

Here is the necessary change:

console_handler.go
```go
<<<<<<< SEARCH
func (c *ConsoleHandler) Log(level slog.Level, message string, data ...slog.Field) error {
	color.New(color.FgBlue).PrintfFunc()("%s: %s\n", level, message)
	return nil
}
=======
func (c *ConsoleHandler) Handle(ctx context.Context, record slog.Record) error {
	color.New(color.FgBlue).PrintfFunc()("%s: %s\n", record.Level, record.Message)
	return nil
}

func (c *ConsoleHandler) Enabled(ctx context.Context, level slog.Level) bool {
	return true
}

func (c *ConsoleHandler) WithAttrs(attrs []slog.Attr) slog.Handler {
	return c
}

func (c *ConsoleHandler) WithGroup(name string) slog.Handler {
	return c
}
>>>>>>> REPLACE
```

This change ensures that the `ConsoleHandler` conforms to the `slog.Handler` interface and uses the correct method signature.
