v0.1.3 - Triton Dependency Fix & Public API Update

v0.1.3 - Triton Dependency Fix & Public API Update

🚀 Summary

This release resolves a critical installation issue on non‑Linux platforms caused by Triton being a hard dependency. It also improves the developer experience by exposing TRITON_AVAILABLE at the package root and updating documentation.

🔧 Changes

• Dependency fix:

  • Removed triton>=3.0.0 from core dependencies.
  • Added optional extra gpu with platform marker (Linux only).
  • Result: pip install flashspec works everywhere; pip install flashspec[gpu] installs Triton on Linux.

• Graceful degradation:

  • Triton kernels wrapped in try/except.
  • Stub functions raise clear ImportError only when called.
  • Added TRITON_AVAILABLE: bool flag.

• Public API:

  • TRITON_AVAILABLE exported from flashspec/__init__.py.
  • Users can check runtime capability directly.

• Tests:

  • Added CPU‑only tests verifying import success, stub behavior, and error messages when Triton is absent.

• CI workflows:

  • Updated pip install steps to request [dev,gpu] / [bench,gpu] where Triton kernels are tested.
  • Ensures GPU tests run only on Linux.

• Docs & metadata:

  • README.md quickstart updated with platform‑specific install notes.
  • CHANGELOG.md documents the fix under [0.1.3].
  • CITATION.cff version bumped to 0.1.3.

⚠️ Important

• Versions 0.1.0–0.1.2 are yanked on PyPI due to broken Triton dependency.
• Please upgrade to 0.1.3 immediately.

📦 Installation

• Cross‑platform (no GPU):

  pip install flashspec

• Linux + CUDA (GPU kernels):

  pip install flashspec[gpu]
