macOS runners now ship with conda-libmamba-solver=25.11.0 pre-installed, which requires conda>=25.9. The old pin to conda=25.3.0 causes a LibMambaUnsatisfiableError because the solver refuses to downgrade conda below its own minimum requirement. Bump the pin to 25.11.1, which satisfies the constraint and has been stable since its release. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Work around conda solver failure on macOS runners where conda-libmamba-solver=25.11.0 conflicts with the conda=25.3.0 pin in pytorch/test-infra's setup-binary-builds action. See: pytorch/test-infra#7951 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
