//! Phase 4 (0.20) — `Tcp.*` helper emitters on `--target wasip2`.
//!
//! Organised by helper family:
//! - [`connect`] — `__rt_tcp_connect`: DNS resolve + create-socket +
//!   start/finish-connect + pool slot allocate + Tcp.Connection
//!   materialise pipeline (the big one, ~700 lines on its own).
//! - [`ids`]      — `__rt_tcp_format_id` / `__rt_tcp_parse_id` for
//!   the `"tcp-N"` slot-id round-trip.
//! - [`io`]       — `__rt_tcp_write_line` / `__rt_tcp_read_line`.
//! - [`lifecycle`] — `__rt_tcp_close` / `__rt_tcp_send` /
//!   `__rt_tcp_ping` (the resource-teardown + orchestrators).
//!
//! Per-helper Index / HelperFns bundles + the matching `emit_*`
//! functions are re-exported here so callers (`module.rs`,
//! `wasip2_tcp_wireup.rs`) get the same surface they had when this
//! module was a single 1945-line file.
