fix(ci): trinity_constants type error, Python ctypes restype, Go test parsing, C++ CMake comment

- Fix trinity_constants.zig: cast u32 to f64 before arithmetic
- Fix Python _binding.py: set restype/argtypes for goldenfloat_phi/trinity
  (ctypes defaults to c_int, returning garbage bit patterns)
- Fix Go gf16_test.go: handle string inputs (inf/nan) from vectors.json
- Fix cpp/CMakeLists.txt: replace // comment with # comment
