Fix macOS CI: pin to macos-15, correct libomp bottle tags#1736
Conversation
The macos-latest runner now resolves to macos-26-arm64 (macOS 26 Tahoe). Homebrew no longer provides sonoma (macOS 14) bottles for libomp 22.1.8. Update the bottle tag to sequoia (macOS 15) which is the latest x86_64 macOS version still supported by Homebrew.

@copilot the CI still fails with |
- Pin test_macos and build_release_macos jobs to macos-15 (Sequoia) instead of macos-latest (now resolves to macos-26-arm64 / Tahoe, which is ARM64-only and cannot fetch x86_64 Homebrew bottles) - Update install-macos.sh to use arm64_sequoia + sonoma bottle tags (the only available ARM64+x86_64 bottle pair in libomp 22.1.8; there is no sequoia x86_64 bottle — sonoma is the last x86_64 one) - Update stale comment in build-macos.sh
