Add a thin, deterministic level loop over the headless model in board.sx:
- target_score: per-level score goal (DEFAULT_TARGET_SCORE=1500), seeded by init.
- Status (in_progress/won/lost) derived purely from score/target/move budget via
level_status; won is checked before lost so meeting the goal on the final move
wins. status_name for the HUD/snapshots.
- has_legal_swap: allocation-free deadlock probe (first legal pair short-circuits).
- reshuffle: Fisher-Yates over existing gems via the board's seeded RNG until the
arrangement has no immediate match and at least one legal move; consumes no
move, terminates via MAX_RESHUFFLE_TRIES.
- restart: reseed a fresh, reproducible level (resets cells/score/moves/goal).
- play_turn / TurnResult: commit_swap then reshuffle on deadlock while in
progress, reporting the resulting status.
tests/level.sx (golden tests/expected/level.{stdout,exit}) asserts: start
in_progress; one legal swap crossing a low goal -> won transition; budget
exhausted below an unreachable goal -> lost transition; a provably deadlocked
diagonal Latin-square board ((col-row) mod 6) reshuffles to >=1 legal move with
no immediate match and no move spent; restart resets progress and a fixed seed
reproduces the same starting board.
Gate: sx build --target ios-sim main.sx (exit 0); bash tools/run_tests.sh
(17 passed, 0 failed).
