ci: enforce strict exit codes in workflow tests

- Remove `|| echo "⚠️ ..."` fallbacks that masked failures
- Add explicit `exit 1` on port readiness failures and missing test directories
- Track port_ready flag in health check loops to fail if services don't start
- Replace warning emoji (⚠️) with error emoji (❌) for actual failures
- Fix docs-validation to use curated Markdown target list excluding high-noise directories
- Update rust-zk-tests paths from gpu_acceleration/research to dev
