* fix(relay): stop rejecting the near region on a cold first probe The region probe counted the process's first /health request, which pays TCP and TLS setup, as a latency sample. The resulting spread rejected the near region on essentially every cold run, leaving the far region as the sole survivor and pinning US desktops to Asia cells for 24 hours. Discard a warm-up probe per origin, compare regions by minimum latency, and keep the spread check only for a genuinely flapping path. A region now wins only against a measured competitor; a rejected or unmeasurable peer sends no hint, which is remembered for an hour so a reconnect does not re-probe. An origin that fails its warm-up is dropped before the sampling rounds, so an unreachable region costs one probe timeout instead of four. After a control socket registers, probe the cell we landed on once per process, and delete the cache only when it names a region other than the best measured one and that cell is more than 3x slower -- a far cell under a correct cache is the director declining the hint, and re-measuring would return the same answer. * test(relay): audit the region probe's global fetch call site
