Track match_play.py's real dependencies (tune_eval_dna.py, filter_pgn.py) and Scott's overnight-SPRT shortcut (test_vs_head.sh); gitignore generated caches/PGN output.

tune_eval_dna.py isn't Texel-tuning-specific tooling anymore -- it's a load-bearing dependency (match_play.py does `from tune_eval_dna import Engine`), so it needs to be tracked for match_play.py to run at all on a fresh checkout, independent of whatever happens to the rest of the auto-tuning pipeline. filter_pgn.py (builds twic_filtered.pgn, the pool match_play.py's --pgn points at) is similarly not tuning-specific. test_vs_head.sh is Scott's shortcut for the overnight SPRT run discussed this session (head_reference/typhoon vs. current build, --games 20000 --workers 20 --st 1 --sprt --elo0 0 --elo1 5). Left untracked, Texel-pipeline-specific and matching this session's move away from auto-tuning: bake_dna.py, dna_diff.py, dna_trend.py, cycle.sh, run_ecm.sh, compare_ecm_*.py, tuned.dna. .gitignore: eval_tune/__pycache__/ and eval_tune/opening_cache/ (pure regeneratable caches) and src/{match_games,self_play_games}.pgn (match_play.py's --pgn-out game logs, generated output not source) -- the dna/first.dna / dna/original_baseline.dna accidental-commit from earlier tonight was exactly this class of mistake, catching the obvious repeat cases now.

Stop tracking pgn data files, ignore pgn/ going forward

These are large generated/downloaded data files (twic.pgn alone is 3.5GB) that don't belong in version control.

Add ignore files.
