docs-archive-performance-records.changed.md

• Superseded measurement records are archived. The September 2026 performance census, execution study and profile and the release comparisons up to 0.10.0 against 0.9.2 move from docs/project/ to docs/project/archive/, indexed by docs/project/archive/README.md; docs/project/ keeps the current comparison, 0.10.1 against 0.10.0, and docs/internals/performance.md the method. The staged plans that built the Python gRPC bindings are removed from docs/internals/design/; the design they implemented is python-grpc-bindings.md.
