5/// Scans the *effective* contents of the game root for renderer driver
6/// DLLs and returns the renderer names available to select, derived from
7/// the `srDD_*.dll` naming pattern (e.g. `srDD_OpenGL.dll` -> `"OpenGL"`).
8///
9/// "Effective" means: real files on disk, minus any the currently-applied
10/// mods hide/replace, plus any a currently-applied mod injects, exactly
11/// what the game's own directory-listing hook would show. This is
12/// [`supreme_fs::GameStorage::list_files`]'s job (it owns all game-file
13/// I/O, mod-awareness included), not something this page resolves itself.
14/// So a mod that ships its own `srDD_*.dll` renderer shows up here too,
15/// not just the vanilla ones physically sitting in `game_path`, as long
16/// as `storage` was actually built hook-aware; with a plain
17/// [`supreme_fs::GameStorage::new`] instance, `list_files` just falls
18/// back to the real files on disk, same as before.
19///
20/// Sorted alphabetically (and deduplicated, courtesy of `list_files`) so
21/// the combo box's entry order is stable across runs.
