bug(upgrade): privacy scrub messaging contradicts footer #549

Description

The upgrade command summary footer states Never touches user state, but the privacy scrub step modifies team.md and agent history.md files (removing emails). This is technically correct behavior (privacy is important), but the messaging is misleading.

Expected Behavior

Footer should accurately reflect what was modified. Suggested text: Privacy scrub may update team.md and history.md to remove email addresses.
