examples/war: working end-to-end War card game ...

A complete, playable port of the card game War: title screen with
0/1/2 player menu, animated deal, sliding cards, deck-count HUD, a
"WAR!" tie-break with buried cards, and a victory screen with a
fanfare. Source split across examples/war/*.ne (constants, assets,
audio, deck/queue logic, RNG, render helpers, and one state file
per game state) and pulled in via examples/war.ne.

Drives nearly every NEScript subsystem at once: custom 88-tile
sprite sheet (card frames, ranks, suits, font, BIG WAR letters);
felt background nametable; pulse-1 / pulse-2 / noise sfx; looping
march on pulse 2; an 8-bit Galois LFSR PRNG; queue-based decks
that conserve cards across rounds; a phase machine inside the
Playing state that handles draw/reveal/win/war/check; and an
autopilot that boots straight into 0-PLAYERS mode so the headless
jsnes harness captures real gameplay at frame 180.

While building this I uncovered five compiler bugs / limitations
in the v0.1 implementation; each is documented with a minimal
reproduction, root cause, current workaround, and proposed fix in
examples/war/COMPILER_BUGS.md. The most painful was the
parameter-VarId aliasing one (#1b) — two functions sharing a
parameter NAME end up sharing a single zero-page slot mapping
across the whole program. Once those compiler bugs are fixed, the
workarounds in war/*.ne should be reverted in the same PR.
