Pull Request Overview

Adds a new boolean flag to the SharedContact message so that contacts can be marked as blocked (ignored).

• Adds should_ignore field to SharedContact in the admin.proto definition
• Includes a comment describing the new field

• [nitpick] The field name should_ignore is a bit verbose and mixes imperative tone; consider renaming to is_ignored or ignored for clearer boolean semantics.

• The comment could be more precise: describe expected behavior when should_ignore is true (e.g., “When true, this contact is added to the ignored list and will not appear in the UI or sync operations.”).

• No tests appear to cover the new should_ignore flag; consider adding unit tests to verify serialization, default behavior (false), and handling in server-side logic.
