fix: StoreKit config path and Swift 6 concurrency warnings

The StoreKitConfigurationFileReference added in #11 used one '../' too
many, resolving outside the repository. Xcode resolves it relative to
the .xcodeproj's xcshareddata directory, so two levels reaches the repo
root.

SweepActivityAttributes is now explicitly nonisolated. The app target
sets SWIFT_DEFAULT_ACTOR_ISOLATION = MainActor while the widget target
does not, so a type shared by both inferred a main-actor-isolated
ActivityAttributes conformance that ActivityKit cannot use from its
concurrent contexts.

LocalAPIService's logger closures captured self strongly while their
inner Tasks declared [weak self]. The weak capture is now on the outer
closure and bound before the Task, so the concurrently-executing closure
references an immutable strong local rather than the weak capture.
