New 255-line test file for zero-allocation integration points API:
- Tests get_gauss_points! function for all topologies
- Validates zero-allocation performance requirement
- Tests return types (NTuple of (weight, ξ) pairs)
- Tests integration point counts for different Gauss orders
- Validates weight sums equal reference element volumes
- Tests usage in assembly loop pattern
- Includes performance benchmarking
Comprehensive test ensuring integration points API provides
zero-allocation compile-time resolved quadrature points.
