Fix test infrastructure and move tests to Xcode build system

- Added Sendable conformance to LocatorType enum to fix concurrency errors
- Fixed SystemSound enum to conform to Equatable, Hashable, Sendable
- Updated test target in Project.swift with proper Swift Testing configuration
- Fixed enum case references (sidebarActivityIndicator → sidebarActivityArea)
- Fixed Criterion property access (isEmpty → attribute/value checks)
- Fixed Locator property access (action → requireAction)
- Added missing .slow tag to SharedTestTags
- Updated timeLimit from deprecated .seconds to .minutes
- Successfully eliminated Swift compiler crash by moving to Xcode build system
