 // ============================================================================
+// Repository Announcement Helper
+// ============================================================================
+
+/// Create a valid repository announcement event for testing sync.
+///
+/// This creates a kind 30617 event with required clone and relays tags.
+/// The event lists all provided domains so it will be accepted by each
+/// relay's write policy.
+///
+/// # Arguments
+/// * `keys` - Keys for signing
+/// * `domains` - Slice of domain strings (e.g., "127.0.0.1:8080")
+/// * `identifier` - Repository identifier (d-tag)
+///
+/// # Returns
+/// A signed repository announcement event ready to send.
