Log Message:
xtrn/zmachine: add the JSZM Z-machine interactive-fiction door

A Synchronet external program (door) that plays Z-machine interactive fiction (Infocom classics and modern IF) in the terminal server, using the JSZM interpreter ported to Synchronet JavaScript (SpiderMonkey 1.8.5).

- jszm.js / quetzal.js -- interpreter engine + Quetzal save codec
- zmachine.js -- the door front-end (v3/4/5/8 text + v6 graphics)
- v6pics.js / v6sixel.js / viewport.js / tools/blorb2gfx.js -- v6 graphics
(SyncTERM APC + Sixel tiers; Blorb->.gfx baker)
- games.ini / getgames.js -- curated game catalog + installer provisioner
(bundles MIT-licensed Zork I/II/III; fetches more on request, incl. Arthur v6)
- install-xtrn.ini -- SCFG auto-install
- test/ -- conformance + unit/smoke suite

Squashed from the standalone jszm development history (process/design docs not included). Original JSZM by zzo38 (public domain); jszm by David Lehenbauer; ES5
port, Synchronet door, v6 graphics, and installer by Rob Swindell (Digital Man).
