v1.1 GPU arc release candidate -- transparent CUDA dispatch on Tegra …

…+ discrete NVIDIA, MPI+CUDA coexistence, 21-gate dispatch surface

Moonlab v0.2.1 -- CA-MPS + var-D + Z2 LGT + gauge warmstart

Headline release: the Clifford-Assisted MPS pipeline lands end-to-end.

  - CA-MPS hybrid representation |psi> = D|phi> with 64x bond-dim
    advantage + 13884x speedup vs plain MPS at n=12 on stabilizer
    states.
  - Variational-D ground-state search with four warmstart strategies
    (IDENTITY, H_ALL, DUAL_TFIM, FERRO_TFIM, STABILIZER_SUBGROUP).
  - First HEP application: 1+1D Z2 lattice gauge theory with exactly
    gauge-invariant kinetic terms.
  - Aaronson-Gottesman symplectic-Gauss-Jordan Clifford builder for
    any abelian Pauli stabilizer subgroup -- generalises across LGT,
    surface/toric/repetition codes, and arbitrary symmetry sectors.
  - CA-PEPS 2D public API scaffold (gate logic in v0.3).
  - Centralised moonlab_status_t registry.
  - Five new symbols on the stable ABI surface, dlsym-pinned.
  - Python bindings for var-D, gauge warmstart, Z2 LGT, status
    stringifier.

90/90 short-tier ctest pass; 96/96 with long-tier including the
kagome 18-site ED cross-check.

v0.2.0 -- Quantum source, quantum safe

First Moonlab release to unify a full-stack quantum simulator with
a full-stack post-quantum cryptography foundation in one library,
driven by the same Bell-verified quantum RNG.

Headline features:
  - FIPS 202 SHA-3 / SHAKE: all NIST KATs pass byte-for-byte.
  - FIPS 203 ML-KEM 512/768/1024: self-regression KAT + NIST-seeded
    KAT via AES-256 SP 800-90A CTR_DRBG (bit-compatible with the
    pq-crystals reference harness).
  - moonlab_mlkemN_keygen_qrng / encaps_qrng: one-call quantum-
    source -> quantum-safe KEM on the stable ABI.
  - Native reverse-mode autograd with CRX/CRY/CRZ + VQE adjoint-
    gradient integration.
  - Error mitigation: ZNE + PEC.
  - Real-space topology via MPO Chebyshev-KPM.
  - Measurement / nonlocality completeness: POVM, weak-Z, quantum
    mutual information, Mermin, Mermin-Klyshko.
  - Device-independent QRNG primitives (Pironio + Toeplitz).
  - Extended noise: composite, convex-mixture, correlated 2q Pauli.

Verification at this tag:
  - 68/68 C ctests green; 126/126 Python pytest green.
  - -Werror Release clean; ASAN + UBSAN clean on all new subsystems.
  - Fresh-clone build verified.
  - External consumer build verified through raw cc, CMake
    find_package, and pkg-config against a prefix install.

narrative, CHANGELOG.md for per-subsystem detail, and
