fix(ci): drop macOS Intel from py3.14 cross-platform set (onnxruntime x86_64 gap) Follow-up to #13772. The new Python 3.14 experimental job on macOS Intel (macos-latest-large / x86_64) fails at dependency resolution: No solution found ... onnxruntime>=1.24.1 has no wheels with a matching platform tag (macosx_*_x86_64) ... onnxruntime>=1.17.0,<=1.23.2 has no cp314 ABI ... lfx==...rc0 depends on markitdown -> magika -> onnxruntime ... unsatisfiable. This is a permanent macOS x86_64 ecosystem gap, not the find-links bug: - langflow pins `onnxruntime>=1.26; python_version>='3.14'` (pyproject.toml), and - onnxruntime dropped macOS x86_64 wheels at 1.24, while the older onnxruntime that still ships macOS x86_64 wheels (<=1.23.2) has no cp314 wheels. So macOS Intel + py3.14 can never resolve. macOS Intel resolves fine through 3.13 (the py<3.14 branch pins onnxruntime<1.24, which still has x86_64 wheels); macOS arm64 has cp314 wheels and is unaffected. The job is non-blocking (continue-on-error) so it never blocked releases, but it's a guaranteed, no-signal failure burning the costly macos-latest-large runner every release. Drop macOS Intel from the 3.14 experimental matrix (keep linux/windows/macOS-arm64) and update the docs/comments to explain the x86_64 wheel gap.
