aider: Update log handlers and CustomLogger to match the slog.Handler interface.

# Aider chat conversation:

USER: ../custom_logger.go:21:7: undefined: slog.SetDefaultLogger

ASSISTANT: The error message indicates that the `slog.SetDefaultLogger` function is not defined. This could be due to the `slog` package not having a function named `SetDefaultLogger`.

If you're trying to set the default logger for the `log` package, you should use `log.SetOutput` function.

Here is the *SEARCH/REPLACE block* to replace `slog.SetDefaultLogger` with `log.SetOutput` in `custom_logger.go`:

USER: update our log handlers to match the slog.Handler interface.  then update our customlogger to also match the slog.Handler interface.

ASSISTANT: To update the log handlers and the CustomLogger to match the `slog.Handler` interface, we need to modify the `console_handler.go`, `json_handler.go`, `relp_handler.go`, `webhook_handler.go`, and `custom_logger.go` files.

Here are the *SEARCH/REPLACE* blocks:
