HDT Collection Exporter by Manacost v1.4.1

Patch release after a Windows and macOS audit.

Fixes

Validates baseline JSON more strictly before using it for changes export. Full export baselines must contain at least one card.
Makes the HSTracker macOS adapter friendlier to HSTracker's Swift 5 project settings by avoiding newer optional-binding shorthand and key-path mapping syntax in user-facing paths.
Prevents the macOS changes export from crashing on duplicate imported baseline keys by replacing trap-prone dictionary construction with explicit lookup builders.
Updates the macOS menu state after saving the current collection as a baseline.

Windows: Hearthstone Deck Tracker plugin DLL, built for x86/.NET Framework.
macOS: source-level HSTracker adapter. HSTracker does not expose the same drop-in plugin mechanism as HDT, so the Swift files must be added to an HSTracker build target.
Export schema remains version 3; no website parser changes are required if it already supports v1.4.0 exports.
