Admin 5fccbadaa8 阶段 C 步骤 7:isa 拆出 Image,vm 依赖收窄。
- 删 isa/Image.h + Image.cpp(ImageView/FNV/写文件/sidecar 不再属于 isa)
- vm 自实现只读视图 vm/Image.h/cpp:头 104(12.13)/段校验/缺 SHA 尾报错
  (型号匹配与 SHA 校验留步骤 8);Machine 改用 vm::Image + vm::ImageHeader
- executor:本地读文件(替换 isa::read_stb_file)
- 测试:isa_test 删映像/FNV 部分;codegen_test/vm_test 改用 compiler::StbView /
  vm::ConstEntry;vm_test 手拼映像适配新格式(头 104 + 尾 32 占位)
- 验证:line1 编译 288 字节 → BytecodeExecutor 回放 Q 正确;ctest 12/12
