feat(browse): Wave-0 Batch F — capture coalescing/cap + AddAdminUI DI registration
Task 10: in-flight coalescing (Lazy<Task<CapturedTree>> keyed on driverType+SHA256(config))
so repeat Browse clicks share one device walk; global SemaphoreSlim cap
(MaxConcurrentCaptures=4) queues excess; per-caller ct via WaitAsync leaves the shared
capture (bounded by open-timeout, CancellationToken.None) unaffected; in-flight-only map
(Refresh = fresh capture). 7 concurrency tests green (158 total in Commons.Tests).
Task 12: AddAdminUI registers IUniversalDriverBrowser->DiscoveryDriverBrowser with
NullDriverFactory fallback (standalone AdminUI => CanBrowse false => manual entry).
AdminUI.Tests 542 green.
