Implement allocate_pty in src/pty.rs: portable_pty openpty + spawn as session leader (set_controlling_tty(true)), with the three-thread blocking→async bridge (REQ-TTY-01): reader → mpsc<Bytes> with zero-length EOF sentinel, writer draining mpsc<StdinCmd> (Bytes/Eof), waiter → oneshot<i32>. TtyHandle.stdout is ReceiverStream<Bytes>, stdin is a StdinSink AsyncWrite wrapper over mpsc::Sender<StdinCmd> (parks a reserve+send future when the channel is full), stderr is None (PTY merges), exit_code is LocalExitFuture. PtyControl implements TtyControl: resize via MasterPty::resize; signal via libc::kill(-pgid, sig) with kill(pid, sig) fallback (Unix, REQ-TTY-02) using alknet_tty::signal_from_name; unknown names and non-Unix fall back to ChildKiller::kill (SIGHUP). LocalExitFuture wraps the oneshot::Receiver<i32> + a ChildKiller kill guard (ADR-056). poll delegates to the receiver and disarms the guard on Ready (no-op Drop on happy path); Drop on cancel calls ChildKiller::kill (SIGHUP) — best-effort; the waiter thread reaps. Bump portable-pty 0.8 → 0.9 to match the POC API (MasterPty: Send). Add tokio-stream, serde_json (dev), tempfile (dev) deps. Tests: happy path (echo), stdin round-trip (cat), resize, signal INT kills child, signal reaches process group (bash -c "sleep 60"), cancel cleanup on drop, unknown signal falls back to ChildKiller.
