The test "TestDial_TransportStoppedDuringRetWait" replaced
tr.dial and tr.ret with test-controlled channels, then called
tr.Start(). Since connManager reads from t.dial, both the test
and connManager were racing to read from the same channel.
Remove tr.Start() since the test manually simulates connManager
behavior.
Also changed some test log formatting to align with other tests.

Enable intrange linter to enforce modern Go range syntax over
traditional for loops, by converting:
for i := 0; i < n; i++
to:
for i := range n
Adding type conversions where needed for compatibility
with existing uint64 parameters.

Ensure Dial exits early or returns error when Transport has been
stopped, instead of blocking on the dial or ret channels. This removes
a potential goroutine leak where callers could pile up waiting
forever under heavy load.
Add select guards before send and receive, and propagate clear error
values so callers can handle shutdown gracefully.
