Rewrite Curator in Rust with an egui GUI

 ## Current state
 
-- Inherited from Tagger: `Tag`, `TagManager`, `File` (sidecar metadata),
-  `FileManager` (folder scan, filtering, ignore patterns), 3-level config,
-  `HardlinkManager` (create/sync/cleanup), pytest suite.
-- Rename Tagger → Curator done across code, spec, config filenames
-  (`.Curator.!gtag` / `.Curator.!ftag`) and tests.
-- **PySide6 GUI** (`src/ui/qt_app.py`) reframed around the Filmotéka workflow is
-  the entry point; the old tkinter `src/ui/gui.py` is retained for reference.
-- **Pool + Filmotéka wired up:** global config holds `pool_dir` / `filmoteka_dir`;
-  `FileManager` creates `Filmy`/`Seriály`, imports movies (copy → `Title.ext`),
-  loads the pool, and the GUI generates the Filmotéka tree via `HardlinkManager`.
-- `File` carries `title` + `csfd_link`. **Pool metadata lives in a unified index**
-  (`<pool>/.Curator.!index`, see `pool_index.py`); `File` writes there when an
-  index is injected. Without an index a `File` is an in-memory object only — the
-  old per-file `.!tag` sidecars and the per-folder `.!ftag` config have been
-  removed.
+- **Rust rewrite (branch `rust`).** Curator is a Rust application: the core
+  (`src/core/`) is a library with the same behaviour and on-disk formats as the
+  Python version (pool index v2, tag schema, naming, global config keys), and
+  the GUI is egui/eframe (`src/ui/`). An existing pool opens unchanged. The
+  Python sources live on in the history of `devel` as the reference.
+- `FileManager` is the service layer; `File` is a view on one media entry of an
+  identity-keyed movie record in `<pool>/.Curator.!index`; series are scanned
+  live from disk.
+- The standalone `tipy-dne` binary replaces `scripts/tipy_dne.py` (which had
+  stopped finding movies after the index moved to v2). The one-off Python
+  migration scripts for old ČSFD tag formats were not ported.
+- Global config moved from `.Curator.!gtag` next to the script to the platform
+  config directory (`CURATOR_CONFIG` overrides it); an old `.Curator.!gtag` in
+  the working directory is picked up on first run.
 
 ### GUI decision
 
-The GUI was **reframed around the Filmotéka** (not kept as a generic tagger) and
-**rewritten in PySide6**: Pool/Filmotéka setup, Import movie, tag-filter sidebar,
-movie table, and one-click Filmotéka generation.
+The GUI is **egui** (eframe): pure Rust, one static binary, straightforward
+Windows builds. It mirrors the PySide6 layout — menu, tag-filter sidebar, movie
+and series table, detail panel, status bar — and every dialog of the Python
+version. Long operations run in background tasks with progress and cancel.
