v0.0.1

Added

• optional rayon feature for internal parallelism
• arc/circle approximation with side selection and polygon/path offsetting
• exact queries (locate, intersects, contains, area, centroid) and validity checks
• snap-rounding noder, plane sweep and boolean operations

Fixed

• reject i64::MIN in opening/closing, range-check shapes and single-vertex paths

Other

• refresh performance table, document rayon and verification; test Send + Sync
• trim concave offset joins at the edge intersection when safe
• satisfy clippy type_complexity in leaf precompute
• end-to-end PCB-like zone fill pipeline
• lazy, leaf-local snap rounding and assembly without re-sorting
• adaptive spatial index for noding and blocked sweep status
• Merge branch 'worktree-agent-a9b88d6dabd25a4db'
• run the Clipper2 differential tests on push and pull requests
• add differential tests against Clipper2 in a standalone oracle crate
• check that the benchmarks compile
• add criterion benchmarks for the spec workloads
• run the fuzz targets weekly and on demand
• add cargo-fuzz targets for every public operation
• hash-based ring linking, split noder phases, float pre-filters for pixel tests
• grid-based noder, single sweep-order sort, float-filtered crossing rounding
• add CI, crates.io, docs.rs and license badges
