The macos-26 runner ships Xcode 26.5 / Apple Clang 21, so the CMake build no longer needs the visibility workaround there. macos-15 (Apple Clang 17) is still affected and keeps the flag. The workaround only ever mattered for CMake builds; b2 defaults to hidden visibility and is unaffected.

Closes #194
