Inject test bundle, add LCOV filter, and test updates

Add an LCOV filtering script and wire it into the CI to strip ignored lines from coverage reports. Include test resources in Package.swift and add a test JSON resource. Introduce a dataBundle property/parameter on SwiftNEW and switch local JSON loading to use the injected bundle so tests can provide .module resources. Add coverage:ignore markers around OS-specific fallbacks to avoid false negatives in Xcode 26 coverage. Refactor several view actions (search toggle, retry load, present release notes) into testable helper methods and expose a testingHistorySheetContent accessor. Add new unit tests to exercise bundle icon lookup, version presentation path, search/retry flows, and local bundle JSON loading.
