X Title: Fix SSL read over-consuming TCP data and ZeroReturn handling by youknowone · Pull Request #7418 · RustPython/RustPython

Description: Use single-record reading (recv_one_tls_record) for all SSL reads, not just handshake. This prevents rustls from eagerly consuming close_notify alongside application data, which left the TCP buffer empty and caused select()-based servers to miss readability and time out. Also fix ZeroReturn to raise SSLEOFError when shutdown has not started, so suppress_ragged_eofs=True can suppress it properly. Summary by CodeRabbit Bug Fixes Simplified SSL/TLS shutdown behavior: peers sending close_notify now result in an immediate empty read (EOF) instead of raising a special exception, reducing ambiguous shutdown outcomes. Refactor TLS record reading reworked to enforce single-record boundaries, avoid draining control records with application data, and maintain correct EOF/select()/non-blocking semantics.
