Implicit import detection covers SPM XCFramework binary modules

tuist inspect dependencies –only implicit now reports source files that import modules exposed by precompiled XCFramework dependencies. Module names from non-target graph dependencies (including XCFramework Info.plist library binary names) are now part of both the implicit import check and the canImport reachability set, so projects using SwiftPM binary targets no longer get false negatives for missing dependency declarations.
