An empty Claude Code session still invokes a nonzero cost!

Expected Behavior

It's not much, obviously, but I would expect zero cost if I didn't use anything.

Actual Behavior

some token usage

Additional Context

I don't _really_ mind the .03 cents cost but I'm wondering whether this is a bug in the cost calculation display or if it's a real charge.
