fix: wrap backend-native exceptions; correct setup/desc docs (v0.1.3)

- CurlCffi/Noble raw_request translate backend-native network errors (curl_cffi
  RequestException, noble_tls TLSClientException) into aiohttp.ClientError so the bare
  request() path gives the same typed-failure contract as the aiohttp backend (L6)
- Noble.setup uses download_if_necessary (the current noble_tls API), with
  update_if_necessary only as a fallback; docstring/CLAUDE.md no longer claim the dead
  'refreshes an existing one' path (L7)
- pyproject description says composition (one injectable TLSSession), not the old
  'ExtendedSession subclasses' (L8).
