//! Import: files and folders (recursive) → photos.
//!
//! 1. Expand folders recursively into supported files (hidden entries and the library's own
//!    folder are skipped), sorted for a stable order.
//! 2. Skip paths already in the catalog.
//! 3. Probe the rest — dimensions, metadata, and the **content hash** of the bytes — in parallel
//!    on native targets.
//! 4. Skip **duplicates by content** (same bytes already in the library, or twice in this batch).
//!    A duplicate (by path or content) of a photo in Recently Deleted is restored instead, with
//!    its edits, unless the import says otherwise ([`OnDeleted`]).
//! 5. *Add* in place (the photo points at the original file), *copy* into the library's
//!    `Originals/YYYY/YYYY-MM-DD/` folder (names made unique) and point at the copy, or *move*
//!    there: placed like a copy (with its XMP sidecars), and the original removed only once its
//!    catalog record is committed and saved (see [`crate::import_move`] for the safety rules).
//! 6. Apply each photo's XMP sidecar (or a raw/DNG file's embedded XMP): the sidecar wins for
//!    metadata and develop settings are restored (see [`crate::sidecar`]). Its capture time fills
//!    in when the file has none (read before step 5, so it also files and names the copy).
//! 7. Optionally apply a preset and add keywords (the import dialog's options).
//! 8. Commit all new photos as one undoable op. (Undoing a move removes the catalog records;
//!    the files stay at the destination — undo never moves files back over a card.)
//! 9. Copy and Move rename sequences use checked platform-sized numbers: the last number is usable once, and any
//!    further renamed files are reported as failed without losing earlier completed transfers.
//!
//! The import dialog first calls [`scan`] (`library.importPreview`): the same expansion, probing
//! and duplicate detection without adding anything, so the user can review the candidates. The
//! probes are kept and reused by the import that follows.
