Log Message:
syncduke: headless door shim -- single-player Duke Nukem 3D over a BBS terminal

Replace Chocolate Duke3D's SDL video/input/timer back end with a headless shim (syncduke_*.c/h) that captures the Build engine's 8-bit framebuffer and renders it to the user's terminal via termgfx -- auto-selecting JPEG XL (on SyncTERM), sixel, or the text/block fallback (so even a no-sixel terminal like conhost works), with F4 to cycle tiers and DSR-ack auto-depth pacing.

Includes the 64-bit (LP64) port of the vendored engine (CON VM + renderer pointer widening), DOOR32.SYS client-socket I/O, the SyncDOOM-style control scheme + mouse steering + Controls Help, per-user save/config dirs (-home), 64-bit-safe save/load, the build script + installer + example config, and a keymap unit test.

v1 is SINGLE-PLAYER ONLY (no multiplayer/lobby/audio yet), shareware Episode 1. See README.md / SEAM.md.
