get_cached_sock() was a new public method that only OTA's fast-select wake filter would ever call. Drop it. The existing public C API already covers this: esphome_lwip_get_sock(fd) looks up a lwip_sock* from a file descriptor (it's exactly what BSDSocketImpl's own constructor calls to populate cached_sock_). OTA uses the public get_fd() + esphome_lwip_get_sock() chain instead — no new Socket accessor, no friend declarations, no layering concerns. The one-time lookup at setup is negligible.
