Add batched GPU simulator and release 0.2.0 - #1

Conversation
Adds a throughput-oriented simulator for dataset generation: thousands of small circuits per batch, one batched matrix product per gate step, on NumPy or CuPy, with Pauli-trajectory noise, readout error, shots and Parquet output. - New westquant_cudaq.batched package, wq-batch CLI and Slurm/A100 scripts. - The module becomes a package; the 0.1.0 API and its tests are unchanged. - Optional extras batched and gpu; plain import stays dependency-free. - Add tests.yml and a test-gated Trusted Publishing publish.yml (the repo had no CI and 0.1.0 was uploaded manually).

Summary
Prepares westquant-cudaq 0.2.0 with the batched GPU simulator for dataset generation (
westquant_cudaq.batched).westquant_cudaq.batched: state-vector simulation of thousands of small circuits (about 2–24 qubits) per batch, on NumPy (CPU) or CuPy (GPU). Supports Pauli-trajectory noise, readout error, shots and Parquet output with provenance. Seedocs/BATCHED.md.wq-batchcommand (run,plan,bench) and Slurm scripts for A100 clusters inscripts/hpc/.westquant_cudaq.pybecomes the packagewestquant_cudaq/. The only change to the former module is__version__plus a lazy__getattr__forbatched, soimport westquant_cudaqstays dependency-free. The 0.1.0 tests are moved totests/unchanged and still pass.batched(numpy, qiskit, pyarrow) andgpu(cupy-cuda12x).CHANGELOG0.2.0, bumpedCITATION.cffto 0.2.0, and added CI:tests.ymlplus the same test-gatedpublish.ymlas the other WestQuant repos.WestQuantOpen/westquant-cudaq/publish.yml/ environmentpypibefore a release can upload. 0.1.0 was uploaded manually.Test plan
