v5.0.0

What's new in 5.0.0

• Added IntShapeResource for borrowing integer paths, shapes, and flat buffers.
• Added lazy float-to-int conversion, iterator area calculations, and coordinate range checks.
• Fixed convexity checks and spike removal when consecutive duplicate vertices are present.
• Updated i_float to 5.0.0.

Breaking changes

• Floating-point resource APIs moved to source::float.
• Floating-point bounds constructors now return Result.
• Removed unused helper APIs.

Migration

Replace source::resource::ShapeResource with source::float::resource::ShapeResource.
For integer resources, use source::int::resource::IntShapeResource.
Update bounds constructor calls to handle errors.
