sane logging defaults for go

# Aider chat conversation:
USER: the init() function in `custom_logger.go` is missing, on package initialization it should replace the log/slog default logger.
ASSISTANT: To add the `init()` function in `custom_logger.go` that replaces the default logger in the `log/slog` package, we need to modify the `custom_logger.go` file.
Here is the *SEARCH/REPLACE block*:
custom_logger.go
```go
<<<<<<< SEARCH
func NewCustomLogger() *CustomLogger {
=======
func init() {
slog.SetDefaultLogger(NewCustomLogger())
}
func NewCustomLogger() *CustomLogger {
>>>>>>> REPLACE
```

simplelog
simplelog is an opinionated logging package designed to facilitate easy and structured logging in Go applications with an absolute minimum of boilerplate.
The idea is that you can add a single import line which replaces the
stdlib log/slog default handler, and solve the 90% case for logging.
Features
- if output is a tty, outputs pretty color logs
- if output is not a tty, outputs json
- supports delivering logs via tcp RELP (e.g. to remote rsyslog using imrelp)
- supports delivering each log message via a webhook
Installation
To use simplelog, first ensure your project is set up with Go modules:
go mod init your_project_name
Then, add SimpleLog to your project:
go get git.eeqj.de/sneak/go-simplelog
Usage
Below is an example of how to use SimpleLog in a Go application. This example is provided in the form of a main.go file, which demonstrates logging at various levels using structured logging syntax.
package main
import (
"log/slog"
_ "git.eeqj.de/sneak/go-simplelog"
)
func main() {
// log structured data with slog as usual:
slog.Info("User login attempt", slog.String("user", "JohnDoe"), slog.Int("attempt", 3))
slog.Warn("Configuration mismatch", slog.String("expected", "config.json"), slog.String("found", "config.dev.json"))
slog.Error("Failed to save data", slog.String("reason", "permission denied"))
}
