When a user rapidly moves waypoints in the Planner, BRouter's thread-priority watchdog kills older in-flight requests to free a thread for newer ones, surfacing to the user as "operation killed by thread-priority-watchdog" errors. Two fixes: 1. Bump the BRouter thread pool on the dedicated host from 4 to 16. `BROUTER_THREADS` is now a Dockerfile ENV (default 4 for flagship/CI/dev) overridden to 16 in `infrastructure/brouter-host/`. The host has 32 GB of RAM and idle cores; 4 threads was a flagship-era constraint that no longer applies. 2. Cancel the previous in-flight `/api/route` request when a new one starts. `use-routing.ts` now keeps an `AbortController` in a ref, aborts it at the top of each `computeRoute`, and bails quietly on `AbortError` so the newer call drives state. Together these eliminate both the "real" contention (at the BRouter level) and the wasted work (BRouter computing a route the client no longer cares about).
