feat: hang-guard request() with an outer asyncio deadline

a backend can lose both its transfer wakeup and its own timeout enforcement in one
failure (observed: a curl_cffi request that parked an aioweb consumer's event loop for
24h+ - loop idle, nothing in flight, the await never completing). wrap _raw_request in
asyncio.wait_for at the effective timeout + 5s slack: the backend's own timeout still
fires first in every healthy failure, the envelope only trips when the backend's timer
is dead, and its cancellation unwedges the orphaned transfer. deadline = per-call numeric
timeout else the session timeout (default 10); timeout=None from request_with_retries
guards on the session bound (that was the wedge path). explicit Session(timeout=None)
stays unguarded - the documented opt-out for genuinely unbounded calls. additive, no new
knob. fired: a never-completing backend hangs forever without this, dies at deadline+slack
with it, and request_with_retries returns a FailureResponse instead of hanging.
