步骤 1:OpFormat/OpClass 显式化 + disasm 表驱动。

- Op.h:新增 OpFormat(RR/RRR/IMM/SLOT/JMP/JC/CALL/CAL/NONE)与
  OpClass(Plain/Instance)枚举;34 条编译期表 kOpDefs(name/format/class,
  与 ops.txt 强校验的基准);mnemonic/format/op_class 查表
- Encode.cpp:disasm 按 format 表驱动输出(文本与之前逐条一致)
- 验证:11 个 ctest 全绿;表查询断言(8 个 INSTANCE=CAL、越界哨兵)
