count quarter turns with blade in Geonum

[mxfactorial]

added

• blade property to Geonum struct to preserve grade information in high dimensions
• blade-aware constructors: from_polar_blade, scalar
• blade helper methods: with_blade, increment_blade, decrement_blade, complement_blade, preserve_blade, with_product_blade
• improved grade extraction using blade property instead of angle-based heuristics
• robust support for million-dimension geometric algebra operations
• explicit blade field assignments in benchmarks
• tests for blade grade preservation in geometric operations
• blade field and optical computing in README

changed

• updated wedge product to use blade property for grade tracking
• updated geometric product to use blade grade arithmetic
• updated differentiation and integration to increment/decrement blade property
• removed angle normalizations to prevent grade information loss
• updated Multivector grade extraction to use blade property directly
• consolidated multivector and blade tests into a single test file

fixed

• fixed high-dimension multivector operations that were failing due to angle normalization
• eliminated angle-based grade inference which was unreliable in high dimensions
• fixed geometric product rule for vector*bivector operations to maintain consistent blade grades
• fixed Clifford conjugate to avoid angle normalizations with TWO_PI
• fixed Geonum initialization in Dimensions::multivector to set blade grades by index
