feat(engine): 四座自动化设施——喷灌 / 收割机 / 售货机 / 磨坊

为什么：自动化建筑只有水井和喂食器，中期以后每天的操作只剩浇水喂食的重复劳动。新设施把"替代行动点动作"的思路推到完整流水线：浇水（井/喷灌）→ 收割机收熟地 → 磨坊把陈粮变饲料 → 喂食器喂牲口 → 售货机趁高价清库存，人不在也能持续产出。 - config.BUILDINGS 注册 4 座：喷灌系统 2800 金（全量浇水）、自动收割机 900 金 ×3（每天各收 2 块熟地，刻意不给经验——机器收的不算劳动，给手动玩法留价值）、自动售货机 1200 金（市价 > 基准价才出手、每天上限 5 份、越贵越先卖）、饲料磨坊 500 金（1 份最便宜的作物磨 3 份饲料）。 - engine._run_buildings 扩成六段流水线，顺序即依赖：磨坊排在喂食器前，早上磨的饲料当天就能喂上；收割机遇满仓停摆、作物留地（同喂食器缺料停摆哲学——自动系统绝不硬来，更绝不自动花钱）。 - webui / build 动作 / catalog 全部由 config.BUILDINGS 驱动，零改动。 - 测试 +6（喷灌全量浇水、收割入库且无经验、满仓停摆留作物、磨坊挑最便宜、磨坊→喂食器同日链路、售货机阈值与配额）。修复断言时确认两个既有行为：引擎自带 START_FEED=5；advance_day 末尾会把动物 fed 复位（"喂到了"的证据是 pending 累计而非 fed 本身）。 - 门禁：534 项 OK（skip 39）、ruff/pyright 全绿。
