R7: trip report + docs/tracker bake-back; mark R7 done

- loadtest/REPORT-R7.md: the final stress-run report — method, the 500-player resource profile, the agreed tuning, the validation (transport_error 2.49% -> 0.72% at 3 gateway cores; the burst run showing connection-bound behavior), and the prod-sizing recommendation for Stage 18. - loadtest/README.md: per-player transports, --cpus capping, docker_stats (was cAdvisor), the absolute BACKEND_DICT_DIR for ./loadtest/... , and report links. - docs/TESTING.md + docs/ARCHITECTURE.md: observability now uses the otelcol docker_stats receiver (cAdvisor removed); links to both trip reports. - CLAUDE.md: repo-layout line reflects docker_stats + per-service limits. - PRERELEASE.md: R7 marked done in the tracker + heading; a Refinements entry recording the decisions, findings, applied tuning and validation. This is the final pre-release hardening phase; Stage 18 (prod cutover) is next.
