[Feature Request] Do not include slash command output in conversation context (/release-notes takes 10% of context alone).

Bug Description
/context and /release-notes consume context.... This is absurd. The default cursor position for /release-notes is to show ALL OF RECORDED HISTORY FOR CLAUDE CODE. 12% of the 1M token context window.... If you were to check your context immediately after doing this, this compounds. Just running context more than once in a row doubles usage. Come on, I know humans don't touch this code any more but... really? At least move the release notes cursor down to not make the default dump the Magnum Opus into your terminal.

Two context runs in a row:
