/api/v1/firewall/checkRun firewall scan against text input
Synchronous firewall scan: runs all enabled layers against the prompt and returns verdict (allow | block) plus per-layer findings. Public p95 SLA: 50 ms. Real CI baseline: 1.13 ms (see scripts/.firewall-latency-baseline.json + ADR-equivalent commit e4191360 for the regression-gate ratchet).
