Close the notable gaps in scripts/run-client-e2e-tests.ps1: - Write round-trip: write a per-client sentinel value to a configurable writable attribute, then assert it is echoed back through the event stream. Extends the Rust mxgw-cli stream-events output with full per-event JSON (itemHandle + protojson-shaped value) so all five language clients run an identical value compare. - Parity: assert an invalid item handle and an unknown session id are rejected rather than silently succeeding. - Auth rejection: assert open-session is rejected with a missing API key and, when -RejectScopeApiKeyEnv is supplied, with an insufficient-scope key. - Parallel: -Parallel runs each language client as an isolated child process and merges their JSON reports. Update docs/GatewayTesting.md for the new phases and flags. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
