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] decmpfs 分块解压欠产出 → 内核堆泄露
-// 分块 zlib 解压的实际产出少于预期时，27.0 不比对 produced 与 expected，内核页缓冲的尾部因此保持未写状态；read() 随后将整个缓冲交回应用，使应用取得陈旧的堆内容。
-// 27.2 补入该比对。
-//
-// [en] decmpfs chunked decompression under-produce → kernel heap disclosure
-// When chunked zlib decompression produces fewer bytes than expected, 27.0 does not compare produced
-// against expected, so the tail of the kernel page buffer is left unwritten; read() then hands the
-// whole buffer back to the app, which receives stale heap content. iOS 27.2 adds that comparison.
-// ── 判别 / oracle ──
-// 这是整套原语中少数完全不需要 entitlement 的内核路径：应用在自身容器内写入一个带 com.apple.decmpfs 扩展属性的文件，读回的内容即内核解压的产物。以 8 字节窗口扫描，
-// 凡落在内核地址空间范围（≥ 0xFFFFFFE000000000）的值即为候选指针。
