 feat(binary): vendor Ghidra 12.1 decompiler + validate P-Code lifting (Phase 0-1) 
Foundation for replacing fold's dead/abstract binary encoder with a real
SSA P-Code frontend. Verified root-cause gap: serializeBinaryIR() emits only
data-discovery nodes (sections/strings/imports/exports); the control-flow
BinaryExprKind values (BasicBlock/CallSite/...) are never constructed, so the
Z3-BB encoder's encodable filter is always empty and encodeBinaryBBs never
runs — hence 0 binary Z3 findings. The P-Code pipeline supersedes that path.

Phase 0 — docs/internal/ghidra-pcode-integration-research.md: P-Code opcode
core, the decompiler C++ embedding API (LoadImage/SleighArchitecture/Funcdata),
the CORE+DECCORE+SLEIGH source sets, no-bison finding, and pypcode as build
reference.

Phase 1 — vendored Ghidra decompiler at pinned commit (Ghidra_12.1_build,
7e89d94e34...) under third_party/ghidra-decompiler/ (cpp + AArch64 specs +
Apache-2.0 LICENSE + VENDOR.md + .gitignore for build artifacts). Validated by
hand on this clang-21/macOS toolchain:
  - full SSA engine (CORE+DECCORE+SLEIGH, 80 files incl. heritage/funcdata/
    action) compiles clean, -std=c++11 -O2, NO BFD, NO bison (generated
    parsers are committed upstream; ruleparse isn't in the lib set);
  - sleigh compiler builds; AArch64 .slaspec -> .sla compiles;
  - tools/pcode_dump.cpp (custom LoadImage, no BFD) lifts the real arm64
    sym._div_by_zero_direct to correct P-Code: `mov w9,#0 -> COPY(const 0)`,
    `sdiv -> INT_SDIV(w8,w9)` — divisor zero-ness explicit in the data flow,
    so the Phase-3 encoder proves div-by-zero trivially, multi-arch.

Not yet meson-wired (next step) and no fold-side IR/encoder yet (Phase 2-3);
this commit is the validated vendor + smoke tool.
