v2.0 — 31 C POC twins + harness fixes

- 31 C POC files, one per CVE folder: full seed construction + trigger +
  main(), self-contained, no app dependency. All compile clean with
  clang -O2 -Wall (zero warnings) on macOS arm64; each has a recorded
  oracle on this host.
- CMGetDMVersionLevelFromRPU ABI pinned by disassembly: macOS export is
  (CFDataRef), the Swift POC drives the 4-arg iOS surface — this is the
  mechanism behind the cm.rpu death oracle on the simulator build.
- Harness fixes: glyphCount guard, MachOInspector size guard, ModTools
  clamp, DeviceModel iPhone19,7, GPTPayload clamps, Gate patch display.
- POC comments rewritten English-only (31 swift + arc.rr + 5 py).
- README (en/zh): C twin column, .c anatomy section, compile/run
  examples, C oracle verification status.
- Dead if-let binding removed from Identity summary; v2.0 build 3.

-// [zh] 沉浸式渲染数据反序列化容量缺失
-// 反序列化取得的 count 与 dataByteSize 仅与「线缆剩余长度」比较，从不与「目标缓冲容量」比较，构成音频服务器进程内的线性堆溢出。27.2 新增 ReadImmersiveRendererDataV1/V2，
-// 将目标容量一并纳入校验，并补入版本号 1..3 的合法性闸门。
-//
-// [en] Immersive renderer data deserialisation capacity gap
-// The count and dataByteSize taken off the wire are compared only against "how much is left on the
-// wire", never against "how much the destination buffer holds", producing a linear heap overflow
-// inside the audio server process. iOS 27.2 adds ReadImmersiveRendererDataV1/V2, folds destination
-// capacity into the check, and adds a version 1..3 validity gate.
