Subject: [PATCH] perf(brain): upgrade to 4 CPU / 4 GiB / 20 instances + rate
 limit WET injector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Cloud Run: 2 CPU → 4 CPU, 2 GiB → 4 GiB, max 10 → 20 instances
- WET injector: 1s delay between batch injects to prevent brain saturation
- Deploy script updated to match new resource allocation
