//! Warn when install targets include AUR rows whose `pkgname` also appears as official in results.

/// What: Build the catalog used to detect AUR vs official duplicates in the current search UI.
///
/// Inputs:
/// - `app`: Live results buffers.
///
/// Output:
/// - Concatenation of `all_results` then `results` (order does not affect detection).
///
/// Details:
/// - Duplicate rows are harmless; [`aur_pkgnames_also_in_official_catalog`] uses a set of official names.

/// What: Open [`crate::state::Modal::WarnAurRepoDuplicate`] when AUR installs shadow official rows.
///
/// Inputs:
/// - `app`: UI state (may set modal).
/// - `packages`: Packages about to be installed.
/// - `header_chips`: Preflight metrics to restore after continue.
///
/// Output:
/// - `true` when the warning modal was shown and the caller must stop the install flow.
///
/// Details:
/// - Honors [`AppState::skip_aur_repo_dup_warning_once`] for the continue path.
