v0.2.1

CI & Repository Improvements

GitHub Actions

• Add path filters to skip CI on docs-only changes
• Switch macOS x86_64 builder to macos-15-intel (native Intel runner)
• Add wheel smoke tests on linux x86_64, windows x64, and macOS
• Switch to PyPI trusted publishing (OIDC) — no more API tokens
• Bump actions/checkout to v6, actions/setup-python to v6
• Add CARGO_INCREMENTAL=0 and PYTHONUTF8=1 env vars
• Rename workflows for clarity: "Build & Release", "Docs"
• Fix docs workflow to skip Rust compilation

Repository Hygiene

• Delete Makefile — justfile covers all recipes
• Migrate from pre-commit to prek (faster Rust-native drop-in)
• Bump ruff from v0.7.2 to v0.15.1

Inspired by polars_ds_extension and pola-rs/polars workflows.
