added logs

resolves Part of #267

Thanks! I think in most cases we don't want to see plenty of such logs. So they'd better be in debug level.

And I think there still be other work to improve logging. So we don't close #267 for now.

I've changed them accordingly.

Yes, I know. I'll add some more in this PR. Please suggest what all to add. Thanks for the help.

Maybe we need to use slog so that we can connect the logs between user invocation and internal requests.

LGTM. Thanks!

In terms of other logging, I think we can have more info! for non-trivial events. Maybe some warn! for unexpected but recoverable errors.
