docs: narrow the per-call impersonate= claim (v0.1.2)

per-call impersonate= is honored only via the low-level request()/_raw_request path
(which forwards **kwargs to the backend), NOT request_with_retries — its inherited
aioweb signature is fixed with no **kwargs and raises TypeError on an extra kwarg.
docs-only across README + backend docstring + CLAUDE.md; for the retrying path, set
the profile on the CurlCffi/Noble instance. no code change.
