Resolves INT-6133.

  • Rename SW_EC_ADD_NE -> SW_EC_ADD_PROJ, SW_EC_DOUBLE -> SW_EC_DOUBLE_PROJ
  • Update memory layout from 2COORD_SIZE to 3COORD_SIZE (projective)
  • Add r32_projective_point notation with X, Y, Z coordinates
  • Update setup validation to check X=modulus, Y=a, Z=b
  • Reference ePrint 2015/1060 complete formulas
  • Update ISA spec, instruction reference, transpiler, RISC-V custom code
  • Update circuit README and user documentation
