feat(telnet,negotiate): NVT negotiation policy — ECHO/NAWS options + mode-aware Negotiator ad1a06234b

telnet.zig grows the two options only plain-telnet hosts negotiate (ECHO/1,
NAWS/31) and buildNaws (RFC 1073 window report, IAC-doubled dimension bytes).
Negotiator gains mode {ibm,nvt}: .nvt accepts DO ttype/naws/sga + WILL echo/sga,
answers TERMINAL-TYPE with the local TERM, volunteers SB NAWS right after WILL
NAWS, and refuses BINARY/EOR (stays plain NVT). In .ibm mode a host WILL ECHO
(Cisco/BBS) or DO NAWS (Unix telnetd) — options no block-mode host negotiates —
sets nvt_seen with no reply and no state flip, so the session can be handed to
the NVT engine which replays the trigger under .nvt policy.

feat(nvt): pure NVT pass-through engine — host/keyboard byte transforms + expect window b56ba70d8a

Engine.feedHost tokenizes the host stream with partial-command carry, passes
data to the terminal (CR NUL collapsed per RFC 854, correct across chunk splits
and around doubled-IAC literals), and answers negotiation with the .nvt policy;
oversized carries or outputs fail closed (error.Overflow ends the session).
feedKeys maps Enter to CR LF, doubles 0xFF, passes ANSI key sequences verbatim,
and reserves Ctrl-] as the local escape. Window gives scripted sessions ordered,
consuming expect matching over a bounded sliding buffer; termType derives the
NVT TERMINAL-TYPE from the local TERM (uppercased, VT100 fallback).

feat(session): surface NVT-host detection from readFrame 1c47660092

When the .ibm negotiator flags nvt_seen (host sent WILL ECHO or DO NAWS —
options no 5250 host negotiates), readFrame returns immediately: pre-trigger
banner bytes stay in rec, pending is rewound to the trigger command, and no
reply is written — the caller hands both buffers to the NVT engine, whose .nvt
negotiator replays and answers the trigger. Callers that can't hand off (probe,
login, --play, the GUI) check session.nvt_seen and refuse cleanly.

feat(tui,main): --nvt plain-telnet mode — interactive pass-through, scripted gate, 5250 auto-fallback 1c67f876f6

Interactive: nvtSession relays bytes between the local terminal and the host
(the enclosing terminal renders, like telnet(1)) over one std.Io.Select with two
persistent reader tasks; the loop re-arms only the completed branch, so socket
writes stay serialized and cancellation only happens at shutdown. NAWS re-reports
on resize at keypress cadence; Ctrl-] disconnects; POSIX-gated (the Windows
console reader is not cancelable).

Scripted: driveNvt is the plain-telnet twin of drive5250/drive3270 — headless
expect/send verbs over a consuming match window, timed reads racing a Select
timer (a read that completes during loser-cancel still counts; an interrupted
one is ignored since a real EOF re-surfaces on the next call), optional raw
asciicast recording (UTF-8-sanitized events, synthetic pacing) for release reels.
drive3270 gains the same --record support for its screen-frame reels.

The default 5250 path hands off transparently on Session.nvt_seen (banner +
still-buffered trigger seed the NVT engine); probe/login/--play/--drive/
probe3270 refuse NVT hosts with a pointer to --nvt instead of hanging.
zelnet <host> works against Cisco/BBS/telnetd out of the box.
