fix(settings): name descending size sort explicitly

The library sort setting used `size` for largest-first sorting while the
ascending option used `sizeAsc`. That made the pair asymmetric and left the
current settings model carrying a legacy-looking key.

Rename the current descending key to `sizeDesc` in the type, menu, and sort
logic. Stored `size` values are normalized to `sizeDesc` on read, so existing
users keep the same largest-first behavior while new writes use the explicit
key.

Test Plan:
- deno task build
- RUSTC_WRAPPER= CARGO_BUILD_RUSTC_WRAPPER= just build
- git diff --check

 ### Install Transactions
 
-Install, update, uninstall, and startup recovery live under `src/install/`.
+Install, update, uninstall, downloaded-file removal, and startup recovery live
+under `src/install/`.
 Each game root has an atomic `.lanspread.json` intent log for install-side
 operations and uses Lanspread-owned `.local.installing/` and `.local.backup/`
 directories marked by `.lanspread_owned`. Startup recovery combines the recorded
 intent with the observed filesystem state and only deletes reserved directories
 when intent or marker ownership proves they belong to Lanspread.
+Downloaded-file removal is deliberately separate from uninstall: it only accepts
+catalog IDs that are direct children of the configured game directory, refuses
