Cookie Auth Consent UX
Phase 16 Step 16.7 adds the explicit opt-in shell for browser cookie auth while preserving manual entry as the default path.
What Changed
- Settings now has an off-by-default browser cookie auth toggle.
- The consent sheet lists supported providers and exact Chrome/Safari cookie-store paths before enabling.
- Denied, unavailable, expired, invalid, and not-found outcomes keep manual entry active with user-facing fallback copy.
- Claude setup and recovery surfaces label cookie-sourced credentials distinctly without rendering secrets.
