fix: feat: evolution-daemon.sh — perpetual evolution loop on DO box (#748)

- Add tools/push3-evolution/evolution-daemon.sh: single-command daemon that
  runs git-pull → apply-patch → clean-tmpdirs → evolve.sh → summary →
  notify → revert-patch → loop, handling SIGINT/SIGTERM cleanly.
- Add tools/push3-evolution/evolution.conf: config file (EVAL_MODE, BASE_RPC_URL,
  POPULATION=20, GENERATIONS=30, MUTATION_RATE=1, ELITES=2, DIVERSE_SEEDS=true,
  GAS_LIMIT=500000, ANCHOR_WIDTH_UNBOUNDED=true).
- Add tools/push3-evolution/evolution.patch: overrides CALCULATE_PARAMS_GAS_LIMIT
  200k→500k in Optimizer.sol + FitnessEvaluator.t.sol, and removes
  MAX_ANCHOR_WIDTH=100 cap in LiquidityManager.sol for unbounded AW exploration.
