v0.3.1 — bug fixes and a docs audit

sweep-solver 0.3.1

A bug-fix and documentation release on top of 0.3.0. Upgrade with
pip install -U sweep-solver. sweepx accepts 0.3.1, but pip install -U sweepx
leaves an installed 0.3.0 solver in place.

Fixed

• cuda_options=CUDAOptions(memory=...) on impl='c' is now read exactly like memory=. Before:

  • Ckpt() and Full() raised at construction.
  • BoundarySaving(storage='cpu', pinned_memory=True) silently ran the GPU ring.

  (#92)

• Curvilinear equations: AcousticCurvilinear and ElasticCurvilinear no longer count as compiled bindings. impl=None on a CUDA device runs them eager instead of raising, and the CLI lists them as eager-only. (#93)

• Domain decomposition: ModelParallel refuses a propagator built with topography= instead of silently decomposing a flat-top problem. (#94)

• Diagnostics: diagnostics()["shim"] reads "pybind" for a SWEEP_BUILD_CUDA=1 install. (#91)

• Stale text: docstrings and error messages for PropBase, PropTorch, the visco-acoustic step, ADCIG, the per-edge free surface and DD. (#95)

Added

• Full, BoundarySaving and Ckpt are importable from sweep.propagator. (#95)

Documentation

• Shorter README and installation page. The release-core build rules moved to Developer › Release cores. (#90, #96)
• The API reference, user guide, examples and notebooks were audited against the code. The audit fixed wrong signatures and defaults, removed APIs, deprecated spellings shown as current, and JIT-era install claims. (#96)

The CUDA cores are the 0.3.0 binaries, unchanged: cu12 c72bdc3a, cu13 10832c06.
