[💡 FEATURE REQUEST]: Add debug mode indication to plugin start log

[Kaspiman]

Plugin

Server

I have an idea!

Hello! I often have to switch between debug mode and back.

It is not always clear what mode the server is in. What if we add this information for each plugin?

For example pool.debug or debug:

{"level":"debug","ts":1728138499360931181,"logger":"http","msg":"http server was started", "pool.debug": "true", "address":"0.0.0.0:8080"}
