The four ReadDeadline(time.Now().Add(2 * time.Second)) calls in
router_integration_test.go (lines 1496, 1543, 1573, 1682) were
producing 'read tcp: i/o timeout' failures in CI under -race while
passing locally. The 2-second window is enough to read the welcome
+ initialState messages on a quiet dev workstation but too tight
once the runner is loaded with cumulative test work and the race
detector overhead. rc.5 cleared the same tests in CI but recent
fixture-size growth (k8s clusters 1->3 in 7938f28de plus the SMART
disk-temperature mock data added in 23ea4e487) pushed the
end-to-end server-start-to-welcome-message latency past the 2s
budget. Bumping to 15s gives CI breathing room without affecting
local test duration (the deadline only takes effect when the read
is genuinely stuck).
