Operation admission withdraws local availability before changing game files.
The UI previously received that withdrawal before the busy state, then
filtered out installations because only downloads counted as local activity.
Publish the active operation first while preserving atomic network withdrawal.
Keep active operations in All Games and Local, retain prior Installed filter
membership until settlement, and show operation-specific status labels. Local
availability and playability remain derived from the backend. Document the
installation presentation and cover withdrawal, settlement, and filter counts.
Test Plan:
- just fmt and just clippy: passed.
- just test: passed all workspace suites.
- just frontend-test: 98 passed, including installation lifecycle regressions.
- deno task build: TypeScript and Vite production build passed.
- Native GUI interaction was not manually exercised.
