Bug Description
Title: understanding changes to Claude Code from within the app itself - example re '/cost'

I noticed a change in how the /cost command reports costs in Claude Code. Previously (in earlier versions), as a Claude Max subscriber,
the cost display seemed to indicate that usage was covered by my subscription.

However, as of some relatively recent version (1.0.3n probably), the /cost command now shows theoretical API costs:

      Total cost:            $0.55
      Total duration (API):  6m 19.7s
      Total duration (wall): 6h 33m 10.2s
      Total code changes:    0 lines added, 0 lines removed

While I understand that as a Claude Max subscriber these costs are already included in my subscription fee, this change in reporting could
cause confusion for users who might think they are being charged additionally. Neither I or the LLM easily found any explanation in
public information.

1. Can you confirm that /cost did change for Max users, in the way I describe?
2. Can you tell me the best way to track and understand these changes?

and really, the bug report / feature request:

1. Provide detailed changelog information in the Claude install that the LLM can access.

Jumping out of the system can be necessary, but it feels weird here.
