add package: pyproject + src

TLSSession over aioweb's backend seam by composition: one session class
delegates the four seams to an injected backend. ships CurlCffi (curl_cffi
impersonate) and Noble (noble_tls Client) backends plus the TLSBackend
protocol for custom clients. tls clients are optional extras
([curl]/[noble]/[all]) with guarded imports; all aioweb features (domain/
header/ephemeral/proxy/retry/preview) inherited unchanged. src/ multi-module
layout, hatchling.
