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.
