cli_v2.py — 一键执行 GDL→IR（v0.95）+ 校验 + 报告
改动要点：
1) policy 默认就是 merge（无需在命令行传参；也可用环境变量 GDL2IR_POLICY 覆盖）
2) 内置 schema 校验 & 自动发现 schema
   - 候选路径依次尝试：
     a) 命令行 --schema
     b) 脚本同目录的 poker_gdl_ir.schema.v0.95.zh.json
     c) 当前工作目录的 poker_gdl_ir.schema.v0.95.zh.json
     d) /mnt/data/poker_gdl_ir.schema.v0.95.zh.json
3) 兼容 validator_v2.validate_with_schema() 返回 2 元组或 3 元组
