fix(ci): resolve processor_tests dependency conflict

Pin agent-framework-orchestrations to the locked 1.0.0b260507 in the
processor_tests install step. The agent-framework-core[all] extra pulls
orchestrations in unpinned, so pip's fresh resolve grabbed the stable
1.0.0 which requires agent-framework-core>=1.9.0, conflicting with the
pinned agent-framework-core==1.3.0 and failing installation.
