APIBypass v0.6.4

Bug Fixes

• Fixed thread safety crashes on macOS 26.5.1: Implemented actor-based architecture for KeychainService and ConfigDataStore to eliminate data races between SwiftUI rendering (main thread) and HTTP request handling (background threads). Previous architecture had unsynchronized dictionary access causing memory corruption and EXC_BAD_ACCESS crashes.

• Fixed JSON serialization crash in FormatTranslator: Removed invalid NSJSONSerialization.dataWithJSONObject: call with String argument. NSJSONSerialization only accepts NSArray or NSDictionary as top-level objects. The system field in Anthropic API now correctly receives a plain string.

• Fixed save button incorrectly enabled on provider selection: Fixed async timing issue where loadOriginalData() was called before keychain finished loading, causing hasChanges to always be true on initial provider selection.

• Fixed MainActor isolation for ConfigManager: Ensured thread-safe access to ConfigManager in HTTP handlers by properly isolating UI-bound properties on @MainActor while background HTTP handlers access the data store directly.
