Phase 2 of the decoupling refactor (behavior-preserving move): - runtime_base.py: RuntimeExecutionError, FeatureExecutionError, ExtentVector - session.py: GeometryAdapter protocol + ExecutionSession - extents.py: end-condition planning (_extent_vectors family) - pattern_transform.py: translate/mirror/rotate replay parameter algebra - runtime.py: keeps executors + registry + entry points; re-exports all moved names (incl. test-referenced privates) for import stability No behavior change; verified against baseline (zero new failures).
