v1.0.0

Added

• IndefiniteLoader<T>, a one-shot loader that drives loading, loaded, and failed
  transitions for a single async operation through two timing rules: a grace delay before any
  loading indicator is shown (0.8 s by default) and a minimum visible duration once one is (1.2 s
  by default). Cached data passed as updating: stays on screen while the operation runs, a
  failure over cached data keeps the data and attaches the error, caller cancellation rewinds to
  the cached value, re-entry cancels the previous load, and an optional timeout fails the
  operation with IndefiniteLoaderError.timedOut.
• IndefiniteLoadState<T> and IndefiniteLoadingPhase, the state the loader emits, with
  Equatable conformance when T is Equatable and the error, isLoadingOrUpdating,
  isLoadingOrUpdatingActive, loadedData, loadingPhase, and updatingPhase accessors.
• IndefiniteLoaderProtocol, the loader's interface, for consumers that substitute their own
  implementation.
• IndefiniteLoaderView, in the IndefiniteLoadingUI product, a SwiftUI view that runs the load
  from its own .task and renders the state through caller-supplied loaded, loading, and
  failed builders, rendering nothing during the grace delay.
• IndefiniteLoadStateView, in the IndefiniteLoadingUI product, a passive SwiftUI renderer for a
  state a view model owns, with loaded, empty, and failure branches and a built-in loading
  view.
• ClockProtocol, SystemClock, and MockClock: the clock the loader sleeps on and reads, the
  production implementation, and a test clock that moves only when a test moves it.
• Two products. IndefiniteLoading carries the loader, its state, and the clock, depends on no UI
  framework, and builds and tests on Apple platforms, Linux, Windows, Android, and WebAssembly
  (WASI). IndefiniteLoadingUI carries the SwiftUI views and compiles to an empty module where
  SwiftUI is unavailable.
