fix(#176): draw-game life capture, DrawGameAnalyzer, clock 6000→3000 (#181)

Captures life-at-timeout snapshots for every draw game via [DRAW] [PARSE-SUMMARY] log lines. Adds services/draw_game_analyzer.py with DrawGameSnapshot + summarize_draw_games(). Wires drawGames summary into GET /api/lab/result response. Lowers batch clock default from 6000 to 3000 (30s per-game). Closes #176.
